On the parabolicity of dipolar exciton traps and their population of excess charge carriers

On the parabolicity of dipolar exciton traps and their population of excess charge carriers

We study spatially trapped ensembles of dipolar excitons in coupled quantum wells by means of photoluminescence and photocurrent spectroscopy. The photogenerated excitons are confined in very clean GaAs double quantum well structures and electrostatically trapped by local gate electrodes. We find th...
