Abstract
We investigated exciton-Zeeman splitting and carrier-spin relaxation in ZnxCd1-xSe/ZnSe multi-quantum wells using magnetic circular dichroic (MCD) measurements and photoluminescence polarization (PLP) spectra. We obtained the exciton-g value from the exciton-Zeeman splitting in the MCD spectra. The well width and Cd composition measurements indicate the possibility of controlling the exciton-g value in a nonmagnetic II-VI compound system. We observed the polarization of the higher exciton levels in the PLP spectra as a result of carrier- spin relaxation. The light hole excitons with positive polarization were affected by the strain induced by the Cd composition in the well layer.
