dc.description.abstract A detailed photoreflectance study of a GaAs-Al0.3Ga0.7As multiple quantum well of well width 260 Å is carried out at 300 and 80 K. The pressure dependence of a large number of quantized states is observed. The sublinearity of pressure dependence increases with increasing quantum number. A model calculation that includes the pressure dependence of electron effective mass accurately describes the data. Transitions associated with L and X band extrema are observed and their pressure coefficients deduced. en
