Quasi-One-Dimensional Electronic Nature of Ta4SiTe4 Underlying the Giant Thermoelectric Performance

Hironari Isshiki, Ayumu Tabata, Masafumi Horio, Motoi Kimata et autres

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 available only in the form of acicular microcrystals, experimental exploration of the electronic properties responsible for its …

Anisotropic optical conductivity accompanied by a small energy gap in the one-dimensional thermoelectric telluride Ta4SiTe4

Fumiya Matsunaga, Yoshihiko Okamoto, Yasunori Yokoyama, K. Takehana et autres

We investigated the optical properties of single crystals of one-dimensional van der Waals crystal ${\mathrm{Ta}}_{4}{\mathrm{SiTe}}_{4}$, which exhibited high thermoelectric performance below room temperature. Optical conductivity estimated from reflectivity spectra indicates the presence of a small energy gap of 0.1--0.15 eV at the …
