Valley-dependent electron-phonon scattering in thermoelectric semimetal Ta${}_2$PdSe${}_6$

Masayuki Ochi, Hitoshi Mori, Akitoshi Nakano

Quasi-one-dimensional transition-metal chalcogenide Ta${}_2$PdSe${}_6$ is a promising thermoelectric semimetal due to the strong electron-hole asymmetry in the carrier lifetime. Howeve…
