## Abstract We studied steep gradients of both chemical composition and residual stress in a Siโdoped GaAs blocking layer of a laser diode by means of spectrally and spatially resolved cathodoluminescence (CL) spectroscopy. Using a lowโenergy electron beam as an excitation source for the CL emissio
