Dependence of gallium nitride nanowires properties on synthesis pressure and temperature
The main task of the investigation was to perform the synthesis of gallium nitride nanowires using a low pressure chemical vapor deposition system. The nanowires were grown via a catalyst-assisted reaction based on the vapor-liquid-solid mechanism. The influence of catalyst, temperature and pressure on the growth of gallium nitride nanowires was explored. Optimal results were obtained at a temperature of 750 oC and at a pressure of 400 to 500 mTorr.
