Observation of ~100% valley-coherent excitons in monolayer MoS2 through giant enhancement of valley coherence time

Abstract In monolayer transition metal dichalcogenide semiconductors, valley coherence degrades rapidly due to a combination of fast scattering and inter-valley exchange interaction. This leads to a sub-picosecond valley coherence time, making coherent manipulation of exciton a highly challenging ta...
