K-point longitudinal acoustic phonons are responsible for ultrafast intervalley scattering in monolayer MoSe2
Valley depolarization processes in 2D transition metal dichalcogenides have been linked to acoustic phonons, but optical verification is ambiguous, due to the nearly degenerate acoustic phonon frequencies at the zone-edge. Here, the authors determine the phonon momentum of the longitudinal acoustic...
