Abstract
We have investigated the exciton spin dynamics in strained InxGa1-xAs/ GaAs (x less-than-or-equal-to 0,2) quantum wells. The variation of the initial polarization with the excitation energy is well correlated wi th the increasing mixing of the valence band states. The time behaviur of the depolarization curves clearly demonstrates the prime importanc e of the hole and exciton spin relaxation processes.
