Amorphous silicon nanowires have been prepared on Si substrates by AuPd nan
oparticles/silane reaction. TEM and SEM have been employed to characterize
the nanowires. The growth mechanism of the nanowires appears to be a vapor-
liquid-solid mechanism. The reasons of forming amorphous silicon nanowires
were discussed. (C) 2000 Elsevier Science Ltd. All rights reserved.
