A study of the process of exciton formation due to acoustic phonon interaction in quantum wells (QWs) is presented. Considering that excitons are formed from photoexcited free electron-hole pairs, we have derived the rate of such formation as a function of density and temperature of charge carriers
Saturation of the D 0 1s-2p + transition, the D --singlet transition and CR has been studied in donor (Si)-doped GaAs/AlGaAs multiple-quantum-well samples by magneto-transmission and magneto-photoconductivity measurements with the UCSB free electron laser. Effective lifetimes of the D 0 1s-2p + tran
