Paper Abstract

We have studied excitonic effects in resonantly coupled GaAs/A1GaAs multiple quantum wells. We use photocurrent spectroscopy to deduce the resonant field from the field-dependent exciton energies, and find an unexpected variation of -10% in the resonant field between different excitonic transitions involving the same coupled electron levels. We construct a variational model of the coupled excitons which explains the results in terms of Coulomb mixing of the delocalised electron states.
