WebPhosphorene, an atomic layer of phosphorus, was realized by the mechanical exfoliation from the layered crystal of black phosphorus (BP) in 2014.1) It is a single component two-dimensional (2D) crystal following graphene and silicene. In contrast to graphene, which is a 2D zerogap conductor, phosphorene is a 2D semiconductor with a finite band gap.
