We report on a comparison of electroluminescence (EL) spectra measured in plan view versus on a cross-sectioned face of the same AlGaN/GaN device for the first time. Because EL emission can be more intense under optically opaque metal structures, a difference was expected. We observed and quantified the difference in EL intensity and the extracted electron… CONTINUE READING
