Natural p–n junctions at the mos2 flake edges
WebThe SnS–WS 2 and SnS–MoS 2 heterostructures exhibited clear rectifying behavior, signifying the formation of p–n junctions at their interfaces. This heterostructure growth combined with the low temperature SnS growth will provide a promising means to exploit two-dimensional heterostructures by avoiding possible damage to the first material.
