Under pressure! The synthesis of crystalline silicon nanowires can be carried out in organic solvents at reaction temperatures of up to 450–500°C under high‐pressure conditions. Gold particles are used as seeds, and organosilanes are employed as the silicon source. The decomposition chemistry of the organosilanes determines the quality of the nanowires formed (see picture of an Si nanowire with an Si/Au tip).
