Abstract: Monolayer black phosphorus (termed 'phosphorene') possesses intriguing tunable electronic properties. Here we report a theoretical study of the antimony analogue of phosphorene, 'antimonene'. Detailed structural parameters and band structures of antimonene films with thickness up to a few atomic layers are obtained by first-principles calculations. Interestingly, a partially degenerate Dirac band emerges in odd atomic layers, which can be attributed to unsaturated bonds and structural flatness.

Keywords: antimonene; black phosphorus; spin-orbit coupling; density functional theory.
