摘要

Two dimensional (2D) materials have been popular recently due to their low-dimensional transport properties. And transition metal dichalcogenides (TMDCs) show a wide range of electronic and optical properties. In this paper, the electronic and optical properties of MoxW1-xS2 alloy such as band structure, bandgap, effective mass and absorption coefficient are modeled sp(3)d(5) by tight-binding model.
