Synthesis of silicon nanowires is studied by using a vapor-liquid-solid growth technique. Silicon tetrachloride reduction with hydrogen in the gas phase is used with gold serving as catalyst to facilitate growth. Only a narrow set of conditions of SiCl4 concentration and temperature yield straight nanowires. High concentrations and temperatures generally result in particulates, catalyst coverage and deactivation, and coatinglike materials.
采用气-液-固生长技术研究了硅纳米线的合成。气相中用氢气还原四氯化硅，并以金作为催化剂促进生长。只有在四氯化硅浓度和温度的一组狭窄条件下才能得到直的纳米线。高浓度和高温通常会导致颗粒、催化剂覆盖和失活以及类涂层材料。
