摘要: 本文利用电弧等离子体蒸发制备了纳米Si纤维通过沉积温度场的调节,确定了纤维的最佳沉积温度约600℃同时表征了纤维的生长过程,在一定的温度下,Si团聚体颗粒间的“颈连接”及颗粒表面的非晶层是导致团聚体自扩散和表面扩散一维生长的直接条件

Abstract:Si nanofiber was prepared by using arc plasma evaporation method. The experimental results revealed that one-dimension growth of the Si particle clusters was responsible for the "neck-connection" between the particle and its surface amorphous layer.Self-diffusion between the particles and surface diffusion on layer of the particle were carried on in various deposition temperature zones.
