Abstract

Measurements of intersubband absorption and cyclotron resonance on lightly-doped GaAs/AlGaAs quantum-well structures with a sensitive optical pumping technique show that the observed intersubband transitions are due to free electrons and that the large photo-generated excess free electron density is due to compensation by acceptors.
