We characterized the interface between the epitaxial layer and substrate of a GaAs wafer by measuring the microscopic photoluminescence (PL) on the cleaved face of the wafer. The intensity of the band-edge PL was higher in the epitaxial layer than in the substrate and locally decreased at the interface. This finding indicates that the non-radiative recombination centers are accumulated at the interface. |
