Fig. 10 — Schematic of the spintronics based on 2D materials. Electrons can be injected into 2D materials to generate spin current (the colors present the different spin) by electrical or optical injection, in which the electrons with different spins diffuse in the opposite direction. The spin could be manipulated by the interface effect of the 2D heterostructure to produce logic signals. (Color figure online)
