Black Phosphorus–Monolayer MoS<sub>2</sub> van der Waals Heterojunction p–n Diode

Black Phosphorus–Monolayer MoS<sub>2</sub> van der Waals Heterojunction p–n Diode

Phosphorene, an elemental 2D material, which is the monolayer of black phosphorus, has been mechanically exfoliated recently. In its bulk form, black phosphorus shows high carrier mobility (~10000 cm2/Vs) and a ~0.3 eV direct bandgap. Well-behaved p-type field-effect transistors with mobilities of up to 1000 cm2/Vs, as well as phototransistors, …
