摘要
Crystalline alpha-Si3N4 nanowires were simply prepared by heating a silicon wafer at 1250 degrees C in a flowing NH3 and N-2 atmosphere. The obtained nanowires are straight and uniform with diameters of 30-100 nm and of lengths up to tens of microns. The possible reactions in the synthesis process are discussed. The growth mechanism of the nanowires is vapor-solid (VS) process.
