Large Thermoelectric Power Factor in One-Dimensional Telluride Nb4SiTe4 and Substituted Compounds
Yoshihiko Okamoto, Taichi Wada, Youichi Yamakawa +2
We found that whisker crystals of Mo-doped Nb4SiTe4 show high thermoelectric performances at low temperatures, indicated by the largest power factor of 70 microW cm-1 K-2 at 230-30…
Large Thermoelectric Power Factor at Low Temperatures in One-Dimensional Telluride Ta4SiTe4
Takumi Inohara, Yoshihiko Okamoto, Youichi Yamakawa +2
We report the discovery of a very large thermoelectric power over -400 microV K-1 in the whisker crystals of a one-dimensional telluride Ta4SiTe4, while maintaining a low electrica…
Low Carrier Density Metal Realized in Candidate Line-Node Dirac Semimetals CaAgP and CaAgAs
Yoshihiko Okamoto, Takumi Inohara, Ai Yamakage +2
We study polycrystalline samples of the hexagonal pnictides, CaAgP and CaAgAs, both of which are ideal candidates for line-node Dirac semimetals. The polycrystalline samples of CaA…
