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 review current research in 2D materials beyond graphene. Our work started with the realisation of the first transistor based on a 2D material other than graphene, a single layer of semiconducting MoS2. Using the MoS2 transistor as a case study, I will present our current level of understanding on the influence of contacts, material quality and the environmental effects on 2D materials, all critical for achieving high performance levels in devices based on 2D materials.
