Ultralow lattice thermal conductivity and excellent thermoelectric performance of monolayer CdGaInS4: A first-principles investigation

Abstract

Monolayer CdGaInSe4 is an excellent optoelectronic material, but its thermoelectric remains unexplored. Through first-principles studies, we investigate the thermoelectric transport properties of monolayer CdGaInS4. Results show that the degenerate weakly...
