The structural and optical properties of green-light-emitting diodes grown by metalorganic chemical vapor deposition technique, were studied using high-resolution transmission electron microscopy, double crystal high resolution x-ray diffraction and low temperature photoluminescence. To study the microstructure of the layers, the back surface of the samples was mechanically polished and then thinned by an Ar + ion milling. A He-Cd laser was used for excitation, and a GaAs based photodetector was used to record excited emission.
