Paper Abstract

Circular photogalvanic effect under interband absorption in quantum wells is considered. The photocurrent is calculated as a function of light frequency for direct transitions between ground electron and hole size-quantized subbands. It is shown that the current spectrum near the absorption edge depends dramatically on the form of spin-orbit interaction: it is a linear function of photon energy in the case of structure inversion asymmetry induced spin-splitting, and it has a parabolic dependence when bulk inversion asymmetry dominates. At higher energies, the existence of a peak in the photocurrent spectrum is predicted.
