Unveiling Ultrafast Spin-Valley Dynamics and Phonon-Mediated Charge Transfer in MoSe${}_2$/WSe${}_2$ Heterostructures

Julian Wagner, Robin Bernhardt, Lukas Rieland +7

We use helicity-resolved ultrafast transient absorption spectroscopy to study spin-valley polarization dynamics in a vertically stacked MoSe${}_2$/WSe${}_2$ heterostructure. The ex…
