Van der Waals Heterostructures Containing Group-III Chalcogenides

The group-III chalcogenides are an emerging class of van der Waals semiconductors with potential for applications in electronics, optoelectronics, and photonics. Further, material properties such as work function and band gap vary dramatically as the material is thinned toward the 2D limit. In this talk, we present experimental studies of the electronic and optical properties of van der Waals heterostructures containing the layered group-III chalcogenides. We analyze the effect of charge transfer within the structure as a function of layer thickness and compare the electronic performance with the more common TMD-based heterostructure devices.
