Abstract

We report changes of the band structure of hexagonal and orthorhombic cells of the monolayer molybdenum disulfide (MoS2) subject to various magnitude and direction of the mechanical strains based on the first principle method. The conduction band minimum (CBM) of this two-dimensional (2D) material h...
