AB INITIO MODELLING OF ELECTRONIC PROPERTIES OF TWO-DIMENSIONAL MOLYBDENUM DISULFIDE

Abstract

The electronic properties of the three- and two-dimensional structures of molybdenum disulfide, formed along <001>, <010>and<100> crystallographic directions, are studied by means of ab initio, from first principles, modeling methods. Electron density and zone structure calculations are performed. It is shown that the zone diagrams of 2D-<010> and -<100> MoS2 are identical. The zone structure of 2D-<001> MoS2 distinguishes by the direct band gap transition and the absence of the additional energetic levels. The detected peculiarities confirm the possibility that MoS2, as well as graphene, possess unique electronic and magnetic properties.
