Research paperComputational DFTTheoreticalSpin Torque Generated by Valley Hall Effect in WSe₂D. J. P. de Sousa, M. J. Sammon, Raseong Kim, Hai Li et al.2022·10.1103/PhysRevB.106.184412·arXiv:2206.09998AbstractThe paper examines spin torque generated through valley Hall effect in a WSe₂ monolayer tunnel junction. Using first-principles electronic structure calculations combined with Bardeen tunneling and drift-diffusion analysis, it shows that a non-equilibrium valley population in monolayer WSe₂ can impart a damping-like torque on an adjacent Fe or CoFe slab, with efficiency tunable by doping and lattice misalignment.Read more
