What can we really expect from 2D materials for electronic applications?

Ultra-thin two-dimensional materials are the recipient of high expectations by both research community and Industry, for their intrinsic electrical properties to be exploited in device applications. While it is nowadays clear that bare graphene will not manage to comply with ITRS [1] requirements for beyond-CMOS devices due to its main limitation i.e., the lack of a bandgap, hopes have been shifted towards 2D heterostructures, as well as alternative two-dimensional materials like Transition Metal Dichalcogenides (TMDs).
