Graphene heterojunction
WebAug 1, 2024 · This paper theoretically calculated halogen-doped graphene/MoS 2 heterojunctions according to the density functional theory. The calculation referred to generalized gradient approximation (GGA). The heterojunction was added 16 Å vacuum thickness to avoid interaction between two adjacent layers.
