ARPES studies and band structure modulation of thermoelectric material SnSe

ORAL

Abstract

SnSe, a group IV-VI monochalcogenide with similar lattice structure to black phosphorus, has recently attracted particular interest due to its excellent thermoelectric properties and potential applications. Here, we present the anisotropic valence bands and multi-valley dispersions which are closely related to its thermoelectric properties on intrinsically semiconducting SnSe crystals by systematic ARPES experiments. Moreover, we carried out the band structure modulation of SnSe and novel phenomena were observed.
