Ultrafast Spin Injection in Graphene via Dynamical Carrier Filtering at Transition Metal Dichalcogenide Interfaces

Shunsuke Yamada, Arqum Hashmi, Tomohito Otobe

We report a real-time first-principles study of ultrafast spin injection in a WSe${}_2$-graphene heterobilayer under circularly polarized laser irradiation, using time-dependent dens…
