Abstract

The photoluminescence (PL) of CdTe/CdMnTe quantum wells (QWs) with well widths from 20 to 150 angstroms has been investigated as a function of hydrostatic pressure (0 - 37 kbar) at liquid-helium temperature. No band crossovers were observed before the phase transition at approximately 33 kbar. Pressure coefficients of the E^(Gamma )_1h transitions between the quantized ground levels of the (Gamma) conduction band and the heavy-hole valence band are presented for various well widths. The pressure coefficient is found to increase with decreasing well widths, as in InGaAs/GaAs strained quantum wells but unlike that observed in the GaAs/AlGaAs quantum well system.
