✦ Synopsis

The exciton dynamics in Zn 1-x Cd x Se/ZnSe multiple quantum wells have been investigated by temperature-dependent time-resolved photoluminescence experiments. A polariton effect (leading to a linear T -dependence of the decay time τ PL ) and thermal escape of carriers from the quantum well at relatively high temperature (resulting in a decrease of τ PL with the temperature) are observed in samples of different stoichiometry and well.

Well-width dependence of quantum and transport mobilities of electrons in GaAs/GaAlAs multiple quantum wells is studied for wells with widths ranging between 50 Å and 145 Å. Experimental results are obtained from the amplitude analysis of the Shubnikov-de Haas (SdH) oscillations and from conventiona
