Please do not adjust margins Please do not adjust margins suppressing short channel effects. By comparison, the minimum channel length that can be achieved in state-of-the-art silicon-based transistors is around 5 nm, which is difficult to reduce further without the device failing. Thus, it is expected that TMDs will be able to enable further reduction in transistor size beyond the intrinsic limit of silicon. There are also other 2D materials that have been successfully exfoliated from their parent materials apart from TMDs, such as phosphole, arsenene, hexagonal boron nitride and C3N4, which have crystal structures similar to that of graphene. In general, these two-dimensional materials have great potential for applications in sensors, batteries, transistors and many other fields, as shown in the Figure . Therefore, there is strong motivation to explore new two-dimensional materials and as such, an expansion of the tools used by researchers to identify and understand 2D materials is desirable for the research community.
