提出了一种制备亚微米硅单晶的液相技术。该合成基于在高温（385 ℃）和高压（>100个大气压）下在非极性有机溶剂中通过钠金属还原SiCl 4和RSiCl 3（R = H，辛基）。对于R = H，合成产生尺寸从5到3000纳米的六边形硅单晶。对于R =辛基，合成也产生六边形硅单晶;然而，尺寸范围控制在5.5 +/- 2.5纳米。
A liquid-solution-phase technique for preparing submicrometer-sized silicon single crystals is presented. The synthesis is based on the reduction of SiCl4 and RSiCl3 (R = H, octyl) by sodium metal in a nonpolar organic solvent at high temperatures (385-degrees-C) and high pressures (>100 atmospheres). For R = H, the synthesis produces hexagonal-shaped silicon single crystals ranging from 5 to 3000 nanometers in size. For R = octyl, the synthesis also produces hexagonal-shaped silicon single crystals; however, the size range is controlled to 5.5 +/- 2.5 nanometers.
