    Outcome：

    2022
    We found that a strong magneto-thermalconductivivty effect was observable for Ag2Te to be used in heat switching devices.

    2022
    We revealed that the lattice thermal conductivity was significantly reduced by anharmonic lattice vibrations and band edge effect in electronic thermal conductivity in Ag2S1-xSex (0≤ x≤ 0.6).
