| Abstract: | A technique involving combined photoreflectance/photoluminescence measurements is proposed to study the electronic properties of semiconductor surfaces. The efficiency of the technique is illustrated by a study of the growth and degradation of the luminescence signal from selenium-passivated GaAs substrates under CW laser excitation. |
