摘要：
Evidence is presented here for significant influence on the surface topography of Ti and Al films in the presence of poly(amidoamine) dendrimer monolayers [generations G(4-8)] on SiOx. X-ray photoelectron spectroscopy analysis clearly indicates formation of nitrides and carbides for Ti metal grown on dendrimer monolayers. In addition, obvious trends in measured correlation lengths and crystalline growth modes of Ti films indicate grain sizes tracking the intrinsic roughness of dendrimer monolayers. No formation of metal nitride is observed for Al depositions. Atomic force microscopy analyses show significant changes in rms vertical roughness and aggregation of as-deposited Ti or Al in presence of dendrimer monolayers. (c) 2006 Elsevier B.V.
