The article shows the most important experimental results describing the properties of nitride layers on GaN single crystals. The layers were grown using metal-organic chemical vapor deposition (MOCVD). The growth was monitored by in-situ laser reflectometry. The layers contain very small dislocation density of about 10 to 103 cm$min2 (the same as in GaN substrates). Morphology and crystallographic quality was examined using atomic force microscopy and X-ray diffraction. The layers have excellent photo luminescent properties which have a direct impact on the optoelectronic device properties.
