Fast and Broadband Photoresponse of Few-Layer Black Phosphorus Field-Effect Transistors
Fast and Broadband Photoresponse of Few-Layer Black Phosphorus Field-Effect Transistors
Few-layer black phosphorus, a new elemental 2D material recently isolated by mechanical exfoliation, is a high-mobility layered semiconductor with a direct bandgap that is predicted to strongly depend on the number of layers, from 0.35 eV (bulk) to 2.0 eV (single-layer). Therefore, black phosphorus is an appealing candidate for tunable …
