HIGHLIGHTS
- who: Qiyao Zhang from the Tsinghua University have published the research work: Prolonging valley polarization lifetime through gate-controlled exciton-to-trion conversion in monolayer molybdenum ditelluride, in the Journal: NATURE COMMUNICATIONS NATURE COMMUNICATIONS
- what: Through the nearresonant excitation, the authors demonstrate the successful observation of PL polarization without a magnetic_field in electrically gated MLMoTe2. The authors show that the PL polarization and depolarization times can be effectively controlled by the gate voltage through different depolarization mechanisms.
SUMMARY
Compared to excitons, the valley-polarization lifetime of trions has been proven to . . .
