Abstract

Thin films of GaN were grown on the Al2O3 (0001) substrate by the laserinduced chemical vapor deposition technique. Morphology were different for the films grown with and without laser irradiation. Moreover, the density of nucleus and the growth rate in the case of the growth with the parallel irradiation were greater than those without irradiation. Differences were attributed to presence of photo-dissociated species in the case of the laser irradiation. Additional irradiation normal to the substrate decreased the rate, probably because of the accelerated desorption of the reactive adsorbed species.
