Twist angle driven electronic structure evolution of twisted bilayer
graphene
In twisted bilayer graphene (TBG) devices, local strains often coexist and entangle with the twist-angle dependent moir\'e superlattice, both of which can significantly affect the electronic properties of TBG. Here, using low-temperature scanning tunneling microscopy, we investigate the fine evolution of the electronic structures of a TBG device with continuous …
