| Research Abstract |
Si and Ge targets are irradiated by pulsed lasers, and the plumes during pulsed laser ablation was collided head-on to prepare hybrid-nanoparticles. The effect of collision was apparent around 300 Pa and was little when gas pressure is much lower or higher. Expansion of plume is molecular flow like at lower gas pressure and is confined at higher background gas pressure. The deposits are nanoparticles of Si and Ge alloy.
