Abstrakt: The results of the first application of electrolyte electroreflectance and photoreflectance to single crystal films of gallium nitride grown by organometallic vapor phase epitaxy on sapphire are presented. Absorption measurements were also performed and used to complement the results of the other techniques. The crystalline quality of the samples was evaluated, and the effects of impurity reductions and different nucleation processes were studied.
