Abstract

We evaluate influence of n-type doping and of the doping level on structural and optical quality of GaN epilayers. We confirm reported previously strong enhancement of light emission from Si doped samples and discuss possible mechanisms of this enhancement. Kelvin probe measurements indicate smoothing of potential fluctuations in the doped layers.
