Higher silanes

WebBy appropriate selection of the higher silane precursor and deposition conditions, silicon deposition can be shifted from amorphous hydrogenated silicon toward microcrystalline silicon structures. ©2013 Gelest,Inc. Volatile higher silanes containing three or more silicon atoms and hydrogen are more accurately termed perhydridooligosilanes. WebThe reaction can produce silanes up to n=15. The reaction of magnesium silicide with 25% hydrochloric acid produces 40% monosilane, 30% disilane, 15% trisilane, 10% tetrasilane and 5% higher silanes. The mixture can be separated by fractional distillation. In addition, higher silanes can also be obtained by discharges monosilane:
