| Outline of Final Research Achievements |
One dimensional nanostructures composed of silicon and germanium are of interest as anode materials of next-generation lithium ion batteries. We performed continuous-wave laser vaporization of germanium/silicon source targets in high-pressure argon gas atmosphere to grow one dimensional nanostructures. Nanotubes and nanowires of silicon-oxide and germanium-silicon-oxide core-shell nanowires were formed depending on the compositions of the targets and the argon pressure. We suggest vapor-liquid-solid mechanisms to grow the nanotubes and nanowires where molten nanoparticles of germanium and silicon act as seeds at high temperature with the contribution of residual oxygen gas.
