Spin/valley pumping of resident electrons in WSe2 and WS2 monolayers

Spin/valley pumping of resident electrons in WSe2 and WS2 monolayers

Optical excitation of transition metal dichalcogenide monolayers mostly generates excitons species with inherently short lifetime and spin/valley relaxation time. Here, the authors demonstrate efficient spin/valley optical pumping of resident electrons in n-doped WSe2 and WS2 monolayers.
