Abstract

Recently there has been a growing interest in the spin relaxation processes of electrons, holes, and excitons in quantum wells.^1-7 This interest is promoted, in part, by the additional information on band mixing and the exchange interaction in quantum wells that can be obtained from the spin relaxation rates of excitons. Two spin relaxation processes are believed to be dominant in GaAs quantum wells, namely, the spin splitting of the conduction band in compounds lacking an inversion symmetry (termed the DP process)⁶ and the spin exchange interaction.⁷
