Unveiling Ultrafast Spin-Valley Dynamics and Phonon-Mediated Charge Transfer in MoSe/WSe 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/WSe heterostructure. The ex…
