本研究では，計算科学的バンド設計に基づいてトポロジーで保護されたエッジモードの発現を予測，力学系にモデル化・可視化，その知見からエッジモードを介した極めて低損失な音波・弾性波伝搬実現を目指している。初年度は各班で以下の取組・成果が得られた。

We propose the development and quantitative interpretation of acoustic and phoxonic metamaterial devices from kHz to GHz frequencies, opening new frontiers in metamaterials. We will generate acoustic waves with frequencies ~0.1 kHz-1 GHz and wavelengths from the millimeter scale down to micro- and nano-scales to control bulk, rod, plate and flexural acoustic waves in both fluid and solid metamaterials, as well as developing the new field of phoxonic, i.e. simultaneous photonic and phononic, metamaterials with the aim to create practical devices. We will investigate metamaterial-based acoustic microscopy, metasurfaces for air-water transmission, lightweight single-component metapillars, metaplates or meta-atoms for wideband multimode acoustic isolation or sub-diffraction limit focusing, as well as the creation of phoxonic metamaterials.

In this project, we have established the experimental method to achieve the time-resolved two-dimensional imaging of GHz surface acoustic waves at arbitrary frequencies. The technique overcomes the restriction of the existing techniques, i.e. the insufficient frequency resolution. The technique can be utilized to the development of materials and devices which exploit surface acoustic waves. We have used the developed technique to study the properties of the phononic band gaps of phononic metamaterials, of the zero group velocity modes of Lamb waves on a plate, etc. We also have established the way to control the chirality of the acoustic field. As a related study, we have designed and fabricated a metamaterial rod structure which shows the perfect band gap, i.e. the band gap for all the possible acoustic modes at certain frequency range.

Elastic property imaging, nanoscale acoustic-optic interactions and defect phonon scattering are investigated. This work should lead to new sensing and imaging technologies.

We investigate gigahertz acoustic metamaterials, extending them to the nanoscale and thus facilitating the development of new nanoscale acoustic microscopies. The aim is to optically generate coherent phonons with frequencies ~1-100 GHz and wavelengths down to ~100 nm in nano-metamaterials to control bulk and surface acoustic waves on very short temporal (~1 ps) and spatial (~20-50 nm) scales. Applications include solid-state super-lensing, extraordinary transmission, negative refraction, surface acoustic wave cloaking, metamaterial resonators and hybrid opto-mechanical materials. We concentrate on three main topics: 1. Design of GHz acoustic metamaterials, 2. GHz extraordinary transmission, metamaterial resonators, and deep-sub-wavelength focusing, 3. Hybrid GHz opto-mechanical metamaterials. During the course of this work a number of supplementary applications were conceived at lower frequencies.

We developed ultrasonic microscopy techniques with high frequencies and high resolutions, aiming to measure and image surface topographies and three-dimensional internal structures of samples. This technique is based on laser picosecond ultrasonics which generate and detect ultrasonic pulses at 10-100 GHz.
We did ultrasonic focusing with micro-structures like a micro-ultrasonic-lens and a micro-fiber, making a smaller probe light spot by use of a high numerical aperture oil-immersion objective lens, high resolution depth-profile ultrasonic measurements in transparent samples, development of arbitrary frequency measurements which are not restricted to repetition pulse laser frequencies, and controlling of pump beam spot shapes.

By means of an ultrafast optical technique, we investigate the coupling of high frequency phonons at GHz frequencies with metallic plasmonic structures. Various samples are probed, including nanovoid arrays, lattices of tiny holes exhibiting extraordinary optical transmission (EOT) and nanoscale linear waveguides. For the nanovoid arrays, we reveal GHz breathing vibrations of the voids by 2D imaging, showing how the vibrations couple to localized Mie plasmons. For the EOT samples, we reveal collective vibration of the hole arrays, and their effect on the optical transmission modulation. For the waveguides we describe work in progress, and fabrication of nanoscale linear gold waveguides.

We aimed to transfer the excitons and to control their life time in semiconductor samples using the surface acoustic waves generated by the ultrashort light pulse absorption. For this purpose, we developed an experimental technique which allows the time resolved two-dimensional imaging of the GHz surface acoustic wave propagation and the two-dimensional imaging of the photoluminescence at the same region of the sample at low temperature (10K). Connecting to this, we also developed a heterodyne technique which use the modulated light for both excitation and probing light. We also developed an analyzing method for the strain components using the polarization of the probing light.

Picosecond acoustic pulses can be used to study the internal structure of medium in nanometer spatial region, or the electron and lattice dynamics of medium in picosecond temporal region. Especially a method named picosecond laser ultrasonics, which uses ultra short light pulses for the generation and detection of the acoustic pulses, has been exploited to evaluate the thickness profile and elastic properties of multilayers, or to study the ultrafast dynamics of photo-induced carriers. In the previous studies, mostly the longitudinal acoustic waves have been used because of the symmetry of the system. However, the additional usage of shear acoustic waves would be favorable to extend the applicability of the method. This research aims to develop the picosecond laser ultrasonics using shear acoustic waves and to apply the method to various studies in materials physics.
The main achievements are as follows. 1) With the low symmetry surface of the anisotropic medium such as Zn and GaAs single crystals, the laser picosecond ultrasonics measurement is carried out. We develop a general light scattering theory for the inhomogeneously modulated multilayers of anisotropic medium. With this theory, the experimental results were quantitatively analyzed to retrieve the photoelastic tensor components, ultrasonic absorption coefficients, electron-phonon interaction coefficients, etc.. 2) We develop a method for the picosecond laser ultrasonics measurement in liquids. The acoustic pulses are generated at the GaAs single crystal and their propagation in water and glycerol is studied. 3) We develop a method to measure the surface displacement caused by the acoustic waves independent of the photoelastic signal. 4) We develop a theory for the acoustic wave propagation in inhomogeneous medium. 5) We develop a method to map the elastic properties of polycrystalline medium with the anisotropic acoustic wave propagation. The method is utilized to study the Cu polycrystals and the artificial phononic crystals.

我々は、ローマ大学「ラ・サピエンザ」のR.Li Voti博士から提供された高精度のTiO_2/Ag多層膜試料を用い、試料中を伝播するピコ秒超音波の広範囲にわたる波長依存性・時間分解の測定を行った。同期した2つの波長可変な超短パルスレーザーシステムを使い、反射率変化の応答を観測した。この試料はフォトニックバンドギャップを波長400nm以下と800nm以上の光に対してもつので、ポンプ光の波長を800nmに固定してプローブ光の波長を400nm付近のバンドギャップエッジの周りで変化させ測定を行った。
プローブ光の波長を400nmから長波長側へ走査し、プローブ光の波長により試料の反射率変化が増大することを発見した。これは、1次元フォトニック構造においてフォトニックバンドギャップが超高速音響光学作用を増大することに利用できることを結論付けるものである。
我々はまた、プローブ光が試料中で多重反射する効果も含めた転送行列法によって、試料中を伝播するピコ秒超音波による反射率変化についての数値的なシミュレーションを行った。この理論結果は、すべてのプローブ光の波長領域において実験結果と一致し、これは初めてフォトニック構造におけるピコ秒時間領域での音響光学変調を定量的に評価したことになる。
この研究は、さらに2次元や3次元フォトニック結晶におけるピコ秒音響光学作用に研究を拡張する基礎となるものである。

1)THz phonon generation and detection experiments were done on 2-well and 3-well GaAs/GaAlAs samples with surface-absorbed probe optical pulses and wavelength-tuned pump optical pulses. These first spectroscopic experiments in the domain of picosecond acoustics (up to 0.3 THz) were successfully treated with theoretical models to describe the phonon generation and detection in these multilayers. We also characterized the spectral generation efficiency.
2)Improvements in temporal and spatial resolution were achieved using shorter (〜400 fs) optical pulses to demonstrate detection at frequencies up to 0.5 THz. We also developed a new optical-polarization-sensitive oblique-incidence technique, tested on Cr, to separate different signal contributions, and modelled the phonon pulse shapes for this sample.
3)A Novel ultrafast Sagnac interferometer was developed for picosecond phonon detection with 1 μm spatial resolution, applicable to semiconductors, involving a single focusing objective.
4)Bulk GaAs picosecond acoustics was implemented to help interpret the quantum well results, we investigated ultrafast phonon generation in 3 different GaAs samples. We demonstrate the generation of picosecond shear pulses using anisotropic cuts and pulse-broadening by electron diffusion.
5)A novel detection scheme based photoluminescence was extensively tested on quantum well samples. The results show that we require a higher detection sensitivity to achieve detection of phonon -pulses detection within a quantum well rather than at the surface.

Imaging of the surface acoustic phonon focusing phenomena reveals complicated patterns of the acoustic energy propagation in anisotropic materials. The imaging technique is expected to play an important role in the development of surface acoustic wave devices in GHz frequency region. In this study, we develop a real-time two-dimensional imaging technique for the surface acoustic wave propagation. It is based on the ultrafast optical pump-probe method and the extremely stable common-path optical interferometer. In case of the diamond substrate covered with Au film, it is shown that the surface acoustic phonon up to 2 GHz is generated and detected by this method. We also develop the analysis method to obtain the multiple mode of the surface acoustic phonon directly from the experimental results on transparent and opaque, isotropic and anisotropic samples.
As a new imaging technique especially for opaque samples, a method using automated mirror is developed. As for the detection of the surface acoustic wave, instead of the interferometer, the method based on the reflectivity change is developed. In relation to this, we develop the light scattering theory that is applicable to the normal and non-normal probe light incidence to the anistropic multilayer sample with inhomogeneous optical properties.
As an application of the technique, the surface acoustic wave is imaged in the poly-crystalline Cu sample consists of micron size grains. The diffraction and reflection at the grain boundary is clearly observed. The result is compared with the simulation based on the FDTD method. It provides the opportunity to evaluate the subsurface structure around the grain boundaries.
In summary, we have developed the general purpose surface acoustic wave measurement and analysis method with pico-second time resolution and micron scale spatial resolutions. By this method, we have clarified the physics of surface acoustic wave propagation in MHz-GHz frequency region.

In this research, we aim to develop a new microscope which has both nanometer spatial resolution and picosecond temporal resolution. It can be realized by the combination of the scanning probe microscope and the time-resolved measurement technique with ultrashort laser pulses. The former has the nanometer spatial resolution and the latter the picosecond temporal resolution. The combination of the ultra high speed optical switch with ultra short laser pulses and the scanning tunneling microscope has been already proposed along this way. It is proved, however, that the stray capacity between the sample and the microscope tip substantially reduces the spatial resolution when the tunnel current is switched very fast. As a way getting around the above problem, we propose a scanning probe microscope that detects ultrashort phonon pulses excited by ultrashort laser pulses.
The ultrashort light pulses from a mode-locked Ti-sapphire laser are divided into two optical paths. An optical delay line is used to introduce a time difference of ± 1 ns between the pulses in two paths. The pulses passing each line are modulated with different frequencies. A metal thin film sample is irradiated by the modulated light pulses to generate the ultrashort acoustic phonon pulses. The generated periodic surface displacement is detected by the atomic force microscopy. We considered this method theoretically and did actual experiments. In addition, we did related studies of the technique to estimate the local elasticity with nanometer spatial resolution by the ultrasonic force microscope and of the ultra high frequency phonon generation by a semiconductor quantum well structure.

本研究は、固体熱物性の空間的分布をナノスケールで画像化できる光学ヘテロダイン原子間力顕微鏡を開発することを目的とした。試料表面においてレーザー照射により光熱的に励起された超音波振動(周波数100MHz以下)の振幅および位相を、ナノメートルの横空間分解能で2次元画像化する。これにより試料表面および表面下の熱的な性質についてのナノメートル空間分解能測定を可能にする。
以下に示すようにして光ヘテロダイン原子間力顕微鏡を構築した。SiN透明カンチレバーを持つ原子間力顕微鏡のカンチレバー支持部に圧電素子をとりつけ、カンチレバーを周波数ω_1=11MHzにて振動させる。探針による試料表面の観察部位にω_1近傍の周波数ω_2で変調された赤外光を照射し試料表面に周期的な熱振動を励起する。試料表面は試料の局所的熱物性を反映してω_2による膨張収縮を繰り返す。試料探針間相互作用の試料探針間距離に対する非線形性により、カンチレバーの平均変位はω_1-ω_2の振動数で変化する。この変化の振幅と位相を原子間力顕微鏡の光てこ検出部を用いて検出し画像化する。試料としてSi基板上にCr薄膜(膜厚100nm)およびSiO_2/Cr薄膜(膜厚150nm/100nm)を作製したものを用いた。これらは同一基板上にμmスケールのモザイク状に形成されている。試料表面層は同一膜厚のCr層で覆われているので、表面から100nm深さまでの機械的な性質は試料表面の場所によらないようになっている。この試料についての光ヘテロダイン顕微鏡による観測を行った。試料表面下のSiO_2層の有無による熱物性の違いを反映して、位相像に大きなコントラストが得られた。1次元熱拡散モデルに基づいてこのコントラストを半定量的に解析した。これらの結果により光ヘテロダイン顕微鏡が試料表面下の局所的熱物性を画像化する有力な手段であることが示された。

In this research, we develop the scanning ultrasonic probe microscope with lateral resolution < 1 nm and study the physics involved in it. The contributions of elasticity, viscosity, surface energy at the sample-tip interface to the sample and cantilever dynamics are analyzed distinctively in order to carry out the quantitative measurement on the surface and subsurface local complex elasticity.
A commercial AFM is modified by attaching the PZT transducer at the cantilever base or on the scanner to make the scanning ultrasonic probe microscopy which is capable to apply the ultrasonic vibration to the cantilever or the sample. At various frequency below and above the cantilever resonance frequency and at various ultrasonic amplitude, we carry out the force curve measurement on Si and GaAs single crystals. The vibration amplitude is calibrated with Michelson enterferomenter. The obtained force curve has the following common features : 1)In case of no applied vibration, small "jump-in" in the approach phase and large "jump-out" in the retraction phase are observed. 2)Within creasing the vibration amplitude, the "jump-out" position rapidly approaches to the "jump-in" position. 3)At above certain vibration amplitude, a new "repulsive jump' is observed for both approach and retraction phase.
These results are analyzed by considering the cantilever motion numerically with the finite difference method. In the analysis, we give the elasticity of the tip and sample, damping, adhesion, and assume the JKR model for the tip-sample interaction. The result explains the features 1)and 2)quantitively and proves the validity of the analysis.

In main aim of this study is to extend our knowledge of ultrafast acoustic phonon generation using femtosecond light pulses to basic metallic materials and nanostructures. The phonon pulse propagation dynamics in such materials and the phonon generation mechanisms can be studied. The use here of a tightly focused excitation and probe light beams a few microns in diameter allow the detection of phonons with -10 μm spatial resolution. In order to do this we have made use of an ultrafast reflectometry and interferometry for measurements at normal incidence.
We have carried out the first generation and detection of coherent phonons in amorphous and liquid metals. The results for Hg demonstrate that electron diffusion is very likely to be influencing the phonon generation. An interesting asymmetric pulse shape was observed. The first demonstration that picosecond phonon pulses could be generated and detected in an amorphous metal was also successful.
Coherent phonon generation and detection experiments in transition metals with -100 fs optical pulses, in particular for Cr and for Ni, shows that we can successfully model the phonon pulse shapes with the two-temperature model, taking due account of ultrasonic attenuation measured in experiment.
Ultrashort optical pulse experiments in transition metals with -10 fs optical pulses have been attempted for the first time. Using a -20 fs order optical pulse width in the infrared for both the pump and probe beams, the effect of ultrafast electron diffusion on ultrashort timescales is clearly evident in the data for a series of films of different thicknesses. A striking reversal in polarity of the signals for thicker films was observed.
Preliminary results for the generation of coherent phonon pulses in multilayer metal structures show that electron diffusion must be taken into account in order to explain the observed acoustic echoes.
Related theoretical work was successful in elucidating the way light is modulated by strain on reflection or transmission through a multilayer structure. This can be done not only for longitudinal coherent phonons but also for shear coherent phonons.

We have presented a comprehensive study of the roles of nanoscopic structural units in chalcogenide glasses in relaxation behaviors around glass transition temperature, structural changes toward crystallization, electronic structures around band-tails, and relaxation processes of photoexcited carriers.
First, we have shown that the variation of Se_n (n>2) chain segments essentially determines relaxational behaviors of networks. We have also shown that the compositional dependence of resonant Raman spectra is explained by the variation in lengths of the Se_n chain and the CST chain. Second, we have found that intrinsic inhomogeneity in Ge-Ge ethan-like units, Se-Se bonds, and fragments similar to β-GeSe_2 can cause significantly different macroscopic structural changes in GeSe_2 glass. Finally, we have demonstrated that threefold-coordinated Se atoms forming Se-Se bonds play a key role in the photoinduced structural change and the dynamics of photoexcited carriers in GeSe_2 glass.

物質の準安定状態であるガラス状態は、通常、熱的な励起により、安定な結晶状態に移行する。アモルファスカルコゲナイド半導体ではこの転移を光照射によって起こすことができる。光には偏光方向の自由度があるので、このような構造変化にかかわる特徴的な方向(例えば結晶軸)を励起光の偏向方向によって制御できる可能性がある。本研究では、光誘起構造変化現象における光励起状態の緩和過程の果たす役割について調べる。
アモルファスカルコゲナイド半導体における、光励起直後の電子励起状態の緩和過程を調べることを目指して。フェムト秒光パルスを用いたポンププローブ超高速過渡的反射率変化測定装置を組み立てた。この測定装置に用いる新しい共通パス型の干渉計を開発した。本装置により試料のピコ秒時間領域の反射率変化および表面変位を検出することができる。
装置の評価のためにアモルファスSi薄膜についての測定を行った。結果を定量的に理解するために、薄膜試料内での熱伝搬、超音波伝搬、電子格子相互作用を考慮したモデルの構築を行った。また、等方的なアモルファス物質中に光によって誘起される非等方的な誘電率変化を検出するための実験配置について詳しい検討を行った。

Amorphous chalcogenide semiconductors which contain the elements of group VI show various kinds of photo-induced structural changes such as photo-darkening, photo-bleaching, photo-crystallization, etc.. These changes are caused by lattice deformations which result from the relaxation of the photo-excited electrons through the strong electron-phonon interaction. It is also important that the amorphous states are not in the thermal equilibrium. The chalcogen atoms which are in two-fold coordinated are considered to play an important role, but the details of the mechanism is still not clear. For example, it is still unknown how the excited electron distorts the lattice.
To know the relaxation process of the excited electron in the amorphous and crystalline GeSe_2 which is a typical chalcogenide semiconductor, the time resolved photo-luminescence measurement was carried out. Both phases have the band-gap in visible region (2.2-2.7eV). The excitation by band-gap light causes a broad Gaussian-shaped photo-luminescence in near-infra-red region (-1eV). The large Stokes-shift is due to the strong electron-phonon interaction. The continuous wave laser light is modulated by an acousto-optic modulator and then used for the excitation source of the time-resolved measurement. The measured time region was 100ns-3ms after the cut-off of the excitation light. There are many similarities in the spectral shape between the amorphous and crystalline GeSe_2. This result shows that the initial states of the luminescence are similar in both materials. As for the time-profile, the crystalline GeSe_2 shows the single exponential decay, while the amorphous GeSe_2 shows the extended exponential decay. The later is caused by the energy distribution of the luminescent centers by structural fluctuation in the glass.
