Band-selective Plasmonic Polaron in Thermoelectric Semimetal TaPdSe with ultra-high power factor
Daiki Ootsuki, Akitoshi Nakano, Urara Maruoka +6
We report the electronic structure of the thermoelectric semimetal TaPdSe with a large thermoelectric power factor and giant Peltier conductivity by means of angle-resolved…
Current-induced successive structural phase transitions beyond thermal equilibrium in single-crystal VO2
Shunsuke Kitou, Akitoshi Nakano, Masato Imaizumi +5
Nonequilibrium systems driven by external energy sources host unexplored physics; yet phase transitions beyond thermal equilibrium remain elusive. Here, we demonstrate that electri…
Current-induced Nonequilibrium Phase Transition Accompanied by Giant Gap Reduction in Vanadium Dioxide
Akitoshi Nakano, Masato Imaizumi, Ichiro Terasaki
We investigated nonlinear conduction in bulk single crystals of VO2 with precise temperature control. Two distinct nonequilibrium phenomena were identified: a gradual reduction of…
Pressure-induced anomalous enhancement in superconducting critical temperature of transition-metal chalcogenide TaPdS and TaPdSe
Ryo Matsumoto, Akitoshi Nakano, Takafumi D Yamamoto +5
The emergence of a second dome in the superconducting phase through pressure-driven manipulation of crystal structures in materials has attracted considerable attention. Transition…
