摘要

1 Introduction Graphene is the first demonstration of a truly 2D atomic layer crystal,and has shown various excellent properties (e.g.,ultrahigh carrier mobility,superior toughness,unique thermal conductivity,and good optics performance).The family of 2D crystals has grown to include metals (e.g.,NbS2,VS2,TaS2),semiconductors (e.g.,MoS2,WS2,ZrS2),and insulators (e.g.,hexagonal boron nitride (hBN)),many of which are stable at ambient conditions [1].
