| Research Abstract |
I have prepared silicon (Si) crystals having the good properties as solar battery materials by using sodium (Na) melt. I presented a phase diagram for Na and Si and made clear that Si crystal dissolves in Na solution at 800-900℃. Based on the phase diagram, I performed formation of single crystals, films, porous bulks and microtubes of Si by vaporizing Na from a Na-Si melt.
