2D dichalcogenide electronic materials and devices

Abstract

The discovery of graphene marked the start of research in 2D electronic materials which was expanded in new directions with MoS₂ and other layered semiconducting materials. They have a wide range of promising potential applications, including those in digital electronics, optoelectronics and flexible devices. Combining 2D materials in heterostructures can increase their reach even further.

In my talk, I will briefly review our research in 2D materials beyond graphene which started with the realisation of the first transistor based on a 2D material other than graphene, a single layer of semiconducting MoS₂. Next, I will present our recent work going in the direction of exploiting the valley degree of freedom for devices that may one day be interesting as an alternative to CMOS.
