Résumé

The temperature (T) dependence of the photoconductivity (PC) in CdCr2Se4 has been measured as a function of In doping with and without Se deficiencies from 80 to 330 °K. In the absence of Se deficiencies or In, the PC is an activated process over much of the T range. When both are present, the PC behavior is more complicated. The PC variations are attributed to lifetime effects rather than to mobility changes. A break in the PC versus T-1 curve, observed near Tc, reflects a dependence of lifetime processes on magnetic ordering.
