With the unique properties, graphene has been widely applied in many fields. Inspired by the excellent structure of graphene, graphene-like materials have been developed. Graphene-like materials are a class of two-dimensional crystal materials, and they can be composed of a single layer or several atomic layers, which are linked by van der Waals forces. Due to the linked mode, the electrons of graphene-like materials can only move freely on the non-na
