Abstract:
1. A method for synthesizing silicon nanowires comprising: feeding a precursor gas into a decomposition zone of a growth reactor; dissociating the precursor gas in the decomposition zone to form an activated species, wherein a decomposition temperature of the decomposition zone is greater than about 350° C.; feeding the activated species to the deposition zone; and reacting the activated species with a catalyst material located in the deposition zone to deposit nano-structured materials on a substrate in the deposition zone, wherein the deposition temperature in the deposition zone is less than about 325° C., further comprising: after the dissociating and before the feeding the activate species to the deposition zone, feeding the activated species to an intermediate zone of the growth reactor; wherein an intermediate temperature of the intermediate zone is less than the decomposition temperature and greater than a deposition temperature of a deposition zone of the growth reactor.
