| Research Abstract |
Laser vaporization was performed using targets of silicon, silicon dioxide, and their mixture without the addition of metal catalysts. From the analysis of the laser-vaporization products, amorphous silicon oxide nanowires having silicon nanoparticles at their tips were found to be grown form silicon and mixed targets. We proposed a novel growth mechanism without the contribution of metal catalysts. We also evaluated the nanowires as an anode material of a next-generation lithium ion battery. The nanowires showed a promising high charge-discharge capacity.
