Abstract:We examine the capabilities of the ab-initio calculations within density functional theory (DFT) on the 2D monolayer MoS 2 , graphene, and Gr-MoS 2 heterostructure.The stability, elastic properties, acoustics, electronic and optical properties of the three hexagonal MoS 2 , graphene, and Gr-MoS 2 heterostructure is presented. The energy bandgap and both Total and partial density of states are calculated within the PBE functional and are enhanced by the HSE06 functional. Gr-MoS 2 hold an indirect bandgap (0.294… Show more
