Cathodoluminescencescanning electron microscopy and positron annihilation techniques have been used to investigate the distribution of defects in GaP wafers. The results show the existence of a gradient of the concentration of vacancy‐type defects along the wafer diameter, which causes inhomogeneity in the emission. Dislocation density and vacancy concentration profiles have been compared.
