Quantum beats of free and bound excitons in GaAs/Al(x)Ga(1-x)As quantum wells
Abstract
We report the observation of quantum beats in the decay of the coherent polarization of intrinsic excitations in GaAs/GaAlAs quantum wells. The beating arises from interference of excitons with slightly different quantum confinement energy due to well-width fluctuations.
