摘要：

We have investigated the effects of compressive uniaxial stress (T) on the photoreflectance spectra at 300K of the fundamental direct band gap (Eo) and its spin-orbit split component (Eo + Δo) of GaAs and Ga0.78Al0.22As for T along [001] and [110]. From the stress-induced shifts and splittings we have deduced the hydrostatic (a) and shear (b and d) deformation potentials of these materials. © 1990.
