摘要

Tiny SiO₂ nano-wires (SiO₂-NWs) were synthesized on a p-Si (111) wafer by the chemical-vapor-deposition method. The minimum diameter of the nano-wires was around 9nm, and the length was longer than 10μm. The results of transmission electron microscopy shows that the amorphous nano-wires were composed of Si and O with an approximate atomic ratio of 1:2. Furthermore, the photoluminescence behavior of the SiO₂-NWs has been also checked.
