Dynamics of bright and dark excitons in a self-assembled quantum dot
We report on a spin-flip process in a charge tunable quantum dot in which a non-radiative dark exciton, with angular momentum L = 2, becomes a radiative bright exciton, L = 1, through interactions with a Fermi sea in an n-doped back contact. This process presents itself by a strongly bias dependent...
