Utilizing interlayer excitons in bilayer WS2 for increased photovoltaic response in ultrathin graphene vertical cross-bar photodetecting tunneling transistors

Abstract:

Here we study the layer-dependent photoconductivity in Gr/WS2/Gr vertical stacked tunneling (VST) cross-bar devices made using two-dimensional (2D) materials all grown by chemical vapor deposition. The larger number of devices (>100) enables a statistically robust analysis on the comparative differences in the photovoltaic response of monolayer and bilayer WS2, which cannot be achieved in small batch devices made using mechanically exfoliated materials. We show a dramatic increase in photo...
