Iv. Lyubinetsky et Vk. Adamchuk, INTERFACE FORMATION DURING SILICON DEPOSITION ON NOBLE-METAL SUBSTRATES - A COMPARATIVE AES STUDY, Thin solid films, 288(1-2), 1996, pp. 182-185
The room-temperature growth of evaporated silicon on copper, silver an
d gold surfaces has been studied by Auger electron spectroscopy. All i
nterfaces, including Si-Ag, are found to be reactive. The formation of
the silicide-like bonds takes place from the very first stages of the
Si deposition and only in an interface layer a few angstroms thick. H
igher coverage results in the growth of a pure continuous Si film. For
Si-Au system our data indicate the silicon diffuses into the gold.
