Tiny SiO2 nano-wires synthesized on Si (1 1 1) wafer

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 View the MathML source, and the length was longer than View the MathML source. 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.
