  English, Scientific journal, ABSTRACT
  
  CeO _{2− δ} (0 ≤ δ ≤ 0.5) has attracted attention as an active material for electrochemical thermal switches that control heat flow electrically because of its wide thermal conductivity ( κ ) switching width between CeO ₂ with fluorite structure (12.5 W m ⁻¹ K ⁻¹ ) and Ce ₂ O ₃ with bixbyite structure (2.2 W m ⁻¹ K ⁻¹ ). Although understanding κ of structurally analogous oxides Ln O ₂ and Ln ₂ O ₃ ( Ln = Pr and Tb) is useful for the selection of active materials for thermal switches, κ of Ln O ₂ and Ln ₂ O ₃ has not been reported due to the lack of single‐phase crystals. In this study, we fabricated Ln O ₂ and Ln ₂ O ₃ ( Ln = Ce, Pr, and Tb) epitaxial films by pulsed laser deposition followed by the electrochemical redox control and measured the κ by time‐domain thermoreflectance method. The oxidized PrO ₂ exhibits markedly lower κ (5.2 W m ⁻¹ K ⁻¹ ) than CeO ₂ or TbO ₂ (10.0 W m ⁻¹ K ⁻¹ ). By comparison, the reduced Pr ₂ O ₃ and Tb ₂ O ₃ display comparable κ values, whereas reduced CeO _x remains multiphase with a slightly lower κ . First‐principles calculation results support the observed κ well. Since the specific heat capacities and densities among these oxides are similar, the present results indicate that the thermal diffusivity of PrO ₂ is intrinsically lower than CeO ₂ or TbO ₂ .

  English, Scientific journal, Abstract
  
  Toward high efficiency energy harvesting device such as thermal transistor, thermal conductivity modulation based on strongly correlated oxides are proposed and explored. High-quality epitaxial film growth of strongly correlated oxides on large area Si substrate is essential to match industrial needs. In this work, LaNiO ₃ thin films are epitaxially grown on buffer layer coated Si(001) substrates. Reversible protonation of the LaNiO ₃ thin film via ionic liquid gating achieves, the thermal conductivity modulation in the range of 0.9 to 3.0 W m ⁻¹ K ⁻¹ , is comparable to that of a prototype laboratory device on single crystal substrate.
