(Invited) Performance of Graphene and Beyond Graphene 2D Semiconductor Devices

Abstract

During the past 10 years, 2D materials have found significant attention in the electronic device community. The first 2D material explored for electronic applications was graphene and the beginning of graphene research was hallmarked by great enthusiasm. It soon turned out, however, that the missing bandgap of graphene causes problems for proper transistor operation and limits the potential of graphene transistors. Therefore researchers have extended their work to 2D materials beyond graphene recently. Meanwhile a variety of different 2D materials are under investigation and part of them has already successfully been used to realize 2D transistors. In the present paper, we introduce the most important 2D materials and evaluate those of their properties relevant for transistors. We review the current state-of-the-art of 2D transistors, compare their performance to that of conventional transistors, and discuss potential applications for 2D transistors.
