WebSep 18, 2024 · Phosphorene, a single layer of black phosphorus, is a direct band gap two-dimensional semiconductor with promising charge and spin transport properties. The electronic band structure of phosphorene is strongly affected by the structural anisotropy of the underlying crystal lattice. We describe the relevant conduction and valence bands … WebAug 19, 2024 · The blue band refers to the valence band, while the red band indicates the conduction band. As can be seen in plots, MBP has a direct band gap. Our band structure shows that the phosphorene band gap in the rest mode, i.e. in the unstrained state, is about 1.52 eV, in good agreement with references [10, 12, 18, 32].

Phosphorene 2D materials are composed of individual layers held together by van der Waals forces in lieu of covalent or ionic bonds that are found in most materials. There are five electrons on 3p orbitals of phosphorus atom, thus, giving rise to sp hybridization of phosphorus atom within phosphorene structure. Monolayered phosphorene exhibits the structure of a quadrangular pyramid be… WebNov 21, 2024 · BP shows semiconducting property due to direct band gap and also tunable as compare to graphene, as a zero band gap semiconductor, according to the applied strain.
