Studies of exchange-induced properties of CdTe{plus 45 degree rule}Cd1-xMnxTe superlattices
Abstract
We report on some magneto-photoluminescence experiments on CdTe{plus 45 degree rule}Cd1-xMnxTe superlattices, which allow the observation of the type-I → type-II transition induced by the giant Zeeman effect of the semimagnetic barrier. The study of the magnetic field, for which the transition occurs, as a function of temperature leads to a determination of the band offset. In addition, several observations about defect luminescence are reported and several specific properties of CdTe{plus 45 degree rule}Cd1-xMnxTe structures are discussed: strain effects on the band offset, exciton binding energy, spin-flip scattering mechanism. © 1992.
