Tunable thermoelectricity in monolayers of MoS${}_2$ and other group-VI dichalcogenides

Abstract

We study the thermoelectric properties of monolayers of MoS${}_2$ and other group-VI dichalcogenides under circularly polarized off-resonant light. Analytical expressions are derived for the Berry phase mediated magnetic moment, orbital magnetization, as well as thermal and Nernst conductivities. Tuning of the band gap by {\it off-resonant} light enhances the spin splitting in both the valence and conduction bands and, thus, leads to a dramatic improvement of the spin and valley thermoelectric properties.
