Magnetothermoelectricity of topological semiconductor ZrTe<sub>5 </sub>

ORAL

Abstract

We report a comprehensive study of electric, thermoelectric, thermodynamic measurements and angle resolved photoemission spectroscopy (ARPES) of the topological insulator candidate ZrTe5. The single crystals grown by a chemical vapor transport method exhibit transport properties characterized by the electronic band structure with a small band gap that is observed by ARPES. The thermoelectricity has a significant response to magnetic field exceeding 300%, for which we discuss the mechanism along with the unique properties of bands deduced from the fermiology.
