Trisilane synthesis
WebColloidal methods are an important type of synthesis approach for semiconductor NWs. Nonetheless, comparing to other semiconductor NWs of group II-VI, III-V and IV, Si is among the most challenging ones, partly due to the fact that Si precursors, such as SiH 4, halogenerated silanes, and organosilanes, are generally very stable and require high … WebTrisilaneis the silanewith the formula H2Si(SiH3)2. A liquid at standard temperature and pressure, it is a silicon analogue of propane. The contrast with propane however trisilane ignites spontaneously in air. [2] Synthesis Trisilane was characterized by Alfred Stock having prepared it by the reaction of hydrochloric acidand magnesium silicide.
