Gallium Nitride films were grown on (111) gallium arsenide substrates using reactive rf magnetron sputtering. Despite a 20% lattice mismatch and different crystal structure, wurtzite. Heteroepitaxy was observed for growth temperatures between 550-600{degrees}C. X-ray diffraction patterns revealed (0002) GaN peak with a full-width-half-maximum (FWHM) as narrow as 0.17{degree}. Possible surface reconstructions to explain the epitaxial growth are presented.
