Observation of Exciton–Exciton Interaction Mediated Valley Depolarization in Monolayer MoSe<sub>2</sub>
The valley pseudospin in monolayer transition metal dichalcogenides (TMDs) has been proposed as a new way to manipulate information in various optoelectronic devices. This relies on a large valley polarization that remains stable over long timescales (hundreds of ns). However, time resolved measurements report valley lifetimes of only a few …
