Abstract

Using first-principles combined with quantum transport calculations, we predict that graphene sandwiched between insulating monolayers of Cr₂Ge₂Te₆ ferromagnet and WS₂ transition-metal dichalcogenide will exhibit spin-orbit torque (SOT) when unpolarized charge current is injected parallel to interfaces of Cr₂Ge₂Te₆/graphene/WS₂ van der Waals (vdW) heterostructure. Although graphene by itself is ...
