Graphene has many intriguing electronic properties. One of note is the absence of backscattering of electrons confined to a single valley. Spin-orbit interactions can allow backscattering, and here, Sun et al. use this spin-orbit coupling dependence of backscattering to measure the strength of the spin-orbit interaction in a graphene/tungsten selenide heterostructure.
