Long valley lifetime of dark excitons in single-layer WSe2

The valley degree of freedom in monolayer transition metal dichalcogenides can be addressed by optical means. Here, the authors develop a waveguide-based method to detect emission from dark excitons in single-layer WSe2, access the valley degree of freedom through the Zeeman effect, and demonstrate...
