Energy-Resolved Photoconductivity Mapping in a Monolayer–Bilayer WSe<sub>2</sub> Lateral Heterostructure
Energy-Resolved Photoconductivity Mapping in a Monolayer–Bilayer WSe<sub>2</sub> Lateral Heterostructure
Vertical and lateral heterostructures of van der Waals materials provide tremendous flexibility for band-structure engineering. Because electronic bands are sensitively affected by defects, strain, and interlayer coupling, the edge and heterojunction of these two-dimensional (2D) systems may exhibit novel physical properties, which can be fully revealed only by spatially resolved …
