Abstract
High-resolution X-ray diffractometry was used to analyze GaN layers grown on sapphire using a metal-organic chemical vapor deposition(MOCVD) method.The crystal structures were determined by the absolute measurement,and the dislocation densities and dislocation torsion angle were determined by the in-plane grazing incidence.
