Quasi-One-Dimensional Electronic Nature of Ta4SiTe4 Underlying the Giant Thermoelectric Performance
Hironari Isshiki, Ayumu Tabata, Masafumi Horio +13
Ta4SiTe4 is a one-dimensional van der Waals material that exhibits an exceptionally large thermoelectric power factor below room temperature. However, since this material has been…
Broken time-reversal symmetry detected by tunneling spectroscopy of superconducting Pd-doped CaAgP
Naoki Matsubara, Rikizo Yano, Kazushige Saigusa +4
The appearance of broken time-reversal symmetry (TRS) in superconducting states is an intriguing issue in solid-state physics because of the incompatibility of the spontaneous magn…
Superconductivity in Ternary Germanide ScPdGe and Silicide ScPdSi
Yusaku Shinoda, Yoshihiko Okamoto, Youichi Yamakawa +4
The electronic properties of ScPdGe and ScPdSi, crystallizing in the hexagonal ZrNiAl and orthorhombic TiNiSi structures, respectively, are investigated. ScPdGe and ScPdSi are foun…
Anisotropic Optical Conductivity Accompanied by a Small Energy Gap in One-Dimensional Thermoelectric Telluride Ta4SiTe4
Fumiya Matsunaga, Yoshihiko Okamoto, Yasunori Yokoyama +7
We investigated the optical properties of single crystals of one-dimensional telluride Ta4SiTe4, which shows high thermoelectric performance below room temperature. Optical conduct…
