The effect of the dislocation line density produced by the relaxation of strain in GaAs/InxGa1-xAs multiquantum wells where x=0.155-0.23 has been studied. There is a strong correlation between the dark line density, observed by cathodoluminescence, before processing of the wafers into photodiode dev...
