Two-dimensional (2D) layered phosphorus possesses multiple structural phases with different properties. By using ab initio approaches, the electronic properties of vertical heterostructured compounds of different structural phases of layered phosphorus have been studied. Both type-I (symmetric) and type-II (staggered) band alignments have been realized in the van der Waals heterostructures. Through appropriate doping, the type-II band alignment can be further tuned to type-III (broken). The multiple types of band alignment suggest great potential of phase manipulated 2D phosphorus for next-generation novel electronics.
