Magnetic field dependent study of transition metal dichalcogenides via time integrated four wave mixing spectroscopy

ORAL

Abstract

Time-integrated four wave mixing measurements were performed on Monolayer WSe2. Magnetic fields up to 7.5 T were applied parallel and perpendicular to the monolayer plane and the dephasing time was measured. Furthermore, the effects of valley spin selection on the dephasing time and the brightening of spin forbidden dark excitons were explored by applying external magnetic fields and by varying the polarizations.
