Electronic and Transport Properties of Bilayer Phosphorene Nanojunction: Effect of Paired Substitution Doping

Electron transport in bilayer phosphorene is studied using the first-principles and nonequilibrium Green’s function formalism. We have explored interlayer properties of a vertically stacked structure with paired substitutional doping. The electron are calculated compared doping, which shows tunable anisotropic nature doped I–V characteristics. Further, to understand role played by dopants, quantum monolayer–bilayer monolayer (ML–BL–ML) nanojunction without dopants. direction-dependent current characteristics discussed different setups. This suggests that dopants play crucial further provided rectifying behavior zigzag direction. Fano resonance also observed as an effect arises from hydrogen-terminated edges interacting second layer. Our study demonstrates significant tuning electronic implying its potential application devices.
