Characteristics of the crystalline and luminescence properties of a plane GaN fi

A-plane GaN films are deposited on (302) \gamma-LiAlO2 substrates by metalorganic chemical vapor deposition (MOCVD). The X-ray diffraction (XRD) results indicate that the in-plane orientation relationship between GaN and LAO substrates is [010]LAO//[0001]GaN and [203]LAO//[1100]GaN with 0.03% and 2.85% lattice mismatch, respectively. Raman scattering results indicate that the strain in the films decreases along with the increase in the thickness of the films. In addition to the band edge emissio
