The resulting heterostructures had high electronic performance, with room-temperature carrier The spin states of single-layer graphene are clearly reflected in the ESR signals. We show the ESR signals of graphene transistors under a wide gate-voltage (V G) region to present the microscopic investigations of the spin states due to the Fermi-degenerate two-dimensional electron system and those due to the atomic vacancies in graphene.

In addition to heterojunctions combining graphene with 2D TMDs, researchers often design multistage carrier transport channels to further improve carrier separation efficiency. The graphene–TMD–graphene sandwich structures for high‐performance photodetectors have been demonstrated as a typical example. Quantum oscillation in carrier transport in two-dimensional junctions Junfeng Zhanga, Weiyu Xie b, Michael L. Agiorgousis b, Duk-Hyun Choe b, Vincent Meunier b, Xiaohong Xu a, Jijun Zhao *c, and Shengbai Zhang *b Two-dimensional (2D) junction devices have recently attracted considerable attention.
