摘要：

We manipulate the center-of-mass motion of excitons by introducing fractions of a monolayer of InAs in bulklike GaAs. Deposition of InAs on various terraced surfaces provides the direct experimental control of the lateral extent of the InAs insertion and thus of the exciton motion. The optical response of excitons attached to these InAs insertions is predominantly determined by the dimensionality of their translational motion.
