Combining two-dimensional (2D) perovskites with other 2D materials to form a van der Waals (vdW) heterostructure has emerged as an intriguing way of designing electronic and optoelectronic devices. The structural, electronic, and optical properties of the 2D (PEA) 2 PbI 4 /black phosphorus (BP) [PEA:(C 4 H 9 NH 3 ) + ] vdW heterostructure have been investigated using first-principles calculations. We found that the (PEA) 2 PbI 4 /BP heterostructure shows a high stability at room temperature. It is demonstrated that the (PEA) 2 PbI 4 /BP heterostructure exhibits a type-I band arrangement with high carrier mobility. Moreover, the band gap and band offset of (PEA) 2 PbI 4 /BP can be effectively modulated by an external electric field, and a transition from semiconductor to metal is observed. The band edges of (PEA) 2 PbI 4 and BP in the (PEA) 2 PbI 4 /BP heterostructure, which show significant changes with the external electric field, provide further support. Furthermore, the BP layers can enhance the light absorption of the (PEA) 2 PbI 4 /BP heterostructures. Our results indicate that the 2D perovskite and BP vdW heterostructures are competitive candidates for the application of low-dimensional photovoltaic and optoelectronic devices. |
