a The monolayer MoS2 in the quasi-two-dimensional plane. Purple and yellow balls represent the molybdenum and sulfur atoms, respectively. This figure is generated by the software VESTA. b The band structure near the K and K′ valleys. c Schematic illustration depicting the valley and spin Hall effects in the monolayer MoS2 without light. When a charge current flows though the sample, the electrons with spins at the K (skyblue) and K′ (pink) valleys move towards opposing transverse sides.
