Synthesis and characterization of nanowires and nanocables

Abstract

The synthesis and characterization of nanowires and nanocables of carbides and nitrides were reported. The carbothermal reduction of SiO 2 xerogel containing carbon nanoparticles in argon was used to prepare SiC nanowires and SiC nanowires sheathed with amorphous SiO 2 coatings (SiC-cored nanocables). Si 3N 4 nanowires were also made by the carbothermal reduction, but the reaction should be carried out in N 2 atmosphere. The gas reaction of Ga 2O vapor with flowing NH 3 was used to form GaN nanowires on a porous alumina template.
