Abstract

Heavy ion elastic recoil detection has been applied to the compositional analysis of polycrystalline GaN films developed for potential, cost-effective use in optoelectronics. Film stoichiometries could be determined to high precision. The films contain significant amounts of oxygen, carbon and hydrogen. AFM microscopy and XRD measurements show that the oxygen content correlates with crystal size. The results are consistent with the preferential incorporation of oxygen at the grain boundaries.
