High-resolution X-ray diffraction synchrotron experiments (Reciprocal Space Mapping) were conducted to investigate the structural quality of Aluminium Nitride and Gallium Nitride layers, which are used for production of blue light emitters.. This study of nanoscale objects generated in semiconductor materials is heading towards producing entirely new device structures relevant to the frontier technologies of photonics and quantum information processing.
