Abstract

A method for determining the coefficient of light attenuation in a thin GaN layer of light-emitting structures is suggested. The method is based on the measurements of electroluminescence intensity in parallel and perpendicular directions to the layer. The light-attenuation coefficient of 90 ± 15 cm−1 was obtained for the GaN layer of an InGaN light-emitting structure.
