Valley-dependent electron-phonon scattering in thermoelectric semimetal TaPdSe
Masayuki Ochi, Hitoshi Mori, Akitoshi Nakano
Quasi-one-dimensional transition-metal chalcogenide TaPdSe is a promising thermoelectric semimetal due to the strong electron-hole asymmetry in the carrier lifetime. Howeve…
Enhanced thermopower in a magnetic semiconductor EuTe4 with multiple charge-density-wave instabilities/
Hidefumi Takahashi, Kiichiro Yoshida, Akitoshi Nakano +1
We investigate the layered magnetic semiconductor EuTe4, focusing on its intricate charge-density wave (CDW) states near and above room temperature through single-crystal X-ray dif…
A rutile-based homologous series Na(PtO) discovered by computationally assisted high-pressure synthesis
Yasuhito Kobayashi, Hidefumi Takahashi, Shunsuke Kitou +4
Layered transition metal oxides typified by the Ruddlesden-Popper phase have been extensively studied for its applications in high-temperature superconductivity, catalysis, and bat…
Observation of converse flexoelectric effect in topological semimetals
Hidefumi Takahashi, Yusuke Kurosaka, Kenta Kimura +2
A strong coupling between electric polarization and elastic deformation in solids is an important factor in creating useful electromechanical nanodevices. Such coupling is typicall…
