We present a symmetry analysis of electronic bandstructure including spin-orbit interaction close to the insulating gap edge in monolayer black phosphorus ('phosphorene'). Expressions for energy dispersion relation and spin-dependent eigenstates for electrons and holes are found via simplification of a perturbative expansion in wavevector $k$ away from the zone center using elementary group theory. Importantly, we expose the underlying symmetries giving rise to substantial anisotropy in optical absorption, charge and spin transport properties, and reveal the mechanism responsible for valence band distortion and possible lack of a true direct gap.

• Modulation of electronic and mechanical properties of phosphorene through strain (2014, background): “In fact, a recent symmetry analysis on undeformed phosphorene has provided a criterion based on which the direct and indirect nature of the band gap can be determined [43].”
