Interface-modulated 2D structures
Monolayer 2D crystals are subjected to surrounding environment since almost all atoms are on their surface. Thus interface plays an important role in 2D crystals and their hybrid structures. "Interface is the devipropertiesce.", this saying has been better supported from the 2D reseach field. In this talk, I introduce some recent progress on interface modulated 2D structures achieved in my group. I will show i) the use of certain substrate to achieve epitaxy for 2D momolayers; ii) substrate-induced moire pattern in graphene and the modulation of its band structure and transport properties; iii) twist-angle modulated transport in MoS2/Graphene heterostructures.
