Germanium Nitride Nanowires Produced by Thermal Annealing in Hydrazine Vapor

• A simple pyrolytic: technology was developed in this paper for producing Germanium nitride nanowires. Hydrazine was used as the nitriding agent, while the 3 mol.% of water diluted in it served for producing volatile GeO molecules and for the accomplishment of mass transfer. The Ge3N4 nuclei appeared on the surfaces of GeOx clusters, formed after redeposition of GeO molecules. The growth of two types of nanowires was observed. The ball-shaped Ge tip surrounded with the amorphous GeO2 sheath served as a catalyst during the vapor-liquid-solid growth of tapered nanowires. Straight nanowires were produced through the oxide-assisted method. Tentative results on the blue-green photoluminescence of nanowires were obtained.
