From Valley Diffusion to Spin Hall and Spin Pumping: Excitonic Spintronics in Monolayer WS₂
Abstract: Monolayer WS₂, a two-dimensional semiconductor, offers coupled spin and valley degrees of freedom that enable innovative “excitonic” spintronics without net charge currents. This article highlights three key developments in WS₂-based exciton spintronics: (1) the real-space imaging of pure spin-valley diffusion currents, (2) the strain-induced …
