Abstract

Photoluminescence spectra of cubic Zn0.82Cd0.18Se quantum wells of widths 30, 60, and 200 are studied as a function of hydrostatic pressure (060 kbar) at 80 K. The pressure coefficients of heavy-hole excitons are found to decrease with increasing well width. The photoluminescence energies of the ZnSe barrier and cap layers are also observed to shift as a function of hydrostatic pressure, providing a measure of the pressure coefficient of the direct gap in this material.
