Charge separation of dense two-dimensional electron-hole gases: mechanism for exciton ring pattern formation.
We report on new experiments and theory that unambiguously resolve the recent puzzling observation of large diameter exciton emission halos around a laser excitation spot in two dimensional systems. We find a novel separation of plasmas of opposite charge with emission from the sharp circular bounda...
