Observation of Dirac-like energy band and ring-torus Fermi surface associated with the nodal line in topological insulator CaAgAs
D. Takane, K. Nakayama, S. Souma +10
One of key challenges in current material research is to search for new topological materials with inverted bulk-band structure. In topological insulators, the band inversion cause…
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…
Crossing-Line-Node Semimetals: General Theory and Application to Rare-Earth Trihydrides
Shingo Kobayashi, Youichi Yamakawa, Ai Yamakage +3
Multiple line nodes in energy-band gaps are found in semimetals preserving mirror-reflection symmetry. We classify possible configurations of multiple line nodes with crossing poin…
