Ab initio density functional theory calculations are performed to study the electronic properties of a MoS 2 monolayer deposited over a SiO 2 substrate in the presence of interface impurities and defects. When MoS 2 is placed on a defect-free substrate, the oxide plays an insignificant role since the conduction band top and the valence band minimum of MoS 2(More)

Two-dimensional (2D) materials are well-known to exhibit interesting phenomena due to quantum confinement. Here, we show that quantum confinement, together with structural anisotropy, result in an electric-field-tunable Dirac cone in 2D black phosphorus. Using density functional theory calculations, we find that an electric field, E ext, applied normal to a(More)
