Giant Peltier Conductivity in an Uncompensated Semimetal Ta2PdSe6
Akitoshi Nakano, Ai Yamakage, Urara Maruoka +3
Thermoelectric properties of single crystal Ta2PdSe6 is investigated by means of transport measurements, and a density functional calculation. We found a giant Peltier conductivity…
Hybridization-gap Formation and Superconductivity in the Pressure-induced Semimetallic Phase of the Excitonic Insulator TaNiSe
Kazuyuki Matsubayashi, Hidekazu Okamura, Takashi Mizokawa +19
The excitonic insulator TaNiSe experiences a first-order structural transition under pressure from rippled to flat layer-structure at Ps = 3 GPa, which drives the system fr…
Room Temperature Thermoelectric Properties of Isostructural Selenides Ta2PdS6 and Ta2PdSe6
Akitoshi Nakano, Urara Maruoka, Fumiaki Kato +2
We have measured thermoelectric properties of Ta2PdX6 (X=S, Se) around room temperature using single crystal samples. We find that the power factor of Ta2PdX6 is relatively high fr…
Weak Ferroelectricity in n = 2 pseudo Ruddlesden-Popper-type niobate Li2SrNb2O7
Takayuki Nagai, Hirokazu Shirakuni, Akitoshi Nakano +4
Li2SrNb2O7 (LSNO) crystallizes in a structure closely related to n = 2 Ruddlesden-Popper-type compounds, which is gen-erally formed by intergrowth of 2-dimensional perovskite-type…
Effect of Cu intercalation and pressure on excitonic interaction in 1T-TiSe2
Shunsuke Kitou, Akitoshi Nakano, Shintaro Kobayashi +9
1T-TiSe2 has a semimetallic band structure at room temperature and undergoes phase transition to a triple-q charge density wave (CDW) state with a commensurate superlattice structu…
Electron-Phonon Coupling Mode in Excitonic Insulator
Akitoshi Nakano, Takumi Hasegawa, Shinya Tamura +3
Ta2NiSe5 is considered a promising excitonic insulator (EI) candidate with slight phonon contributions, since it exhibits a tiny orthorhombic-to-monoclinic structural distortion at…
