Abstract
Silicon nanowires (SiNWs) have been fabricated with metal- and SiO/sub 2/-catalyses assisted by laser ablation. In the growths of single-crystalline SiNWs by metal-catalysts, it is found that SiNWs are along growth direction; however, the growth direction is resulted in the SiO/sub 2/-catalyzed SiNWs. Pressure effect on the longitudinal and transverse growing rates of these SiNWs has also been examined. With the chemical vapor deposition method, the silica nanotubes (SiO/sub 2/NTs) could be achieved with Au nanoparticles as catalysts. From electron diffraction pattern, it shows that the SiO/sub 2/NTs are amorphous and the possible growth mechanism would be discussed.
