Electron spin resonance driven photogalvanic effect in graphene-based structures
C. Bray, I. Yahniuk, L. E. Golub +13
We report an electron-spin-resonance-driven linear photogalvanic effect (LPGE) in unbiased monolayer graphene and WSe_2/graphene heterostructures. Under linearly polarized 45--75 G…
