Research output: Chapter in Book/Report/Conference proceedingConference contribution


We investigated spin-valley dynamics of excitons and trions in electrically-gated monolayer MoTe2 using helicity-resolved quasi-resonant pump-probe spectroscopy. Trion valley polarization was observed for the first time in MoTe2, with initial polarization degree up to 60%.
