Abstract

Spatially resolved photoluminescence spectroscopy was employed to investigate the dynamic control of excitons in GaAs/AlGaAs double quantum wells within the confined and moving potentials formed by the interference of orthogonal surface acoustic waves. We demonstrate the unique ability of these dynamic strain dots to transport photogenerated indirect excitons over macroscopic distances.
