| Outline of Final Research Achievements |
We explored methods for controlling exciton valley polarization in optically excited transition metal dichalcogenides. As a major achievement, we found that the valley polarization of excitons in monolayer tungsten diselenide can be tuned through modulations in carrier density, exciton linewidth, and exciton lifetimes induced by stacking on thin multilayer graphene substrate.
