Detection of spin excitation transfer in a two-dimensional electron system via photoluminescence of multiparticle exciton complexes

详细

The possibility of creating dense ensembles of spin excitons, transferring them to macroscopic distances on the order of hundreds of microns, and recording the appearance of these excitons in the region spatially remote from the excitation point by means of simple techniques of photoexcitation and space-resolved detection of photoluminescence of a two-dimensional electron gas in a GaAs/AlGaAs quantum well has been demonstrated.
