Abstract

11-Aminoundecanoic acid capped titanium dioxide (capped-TiO₂) nanoparticles (63±2 angstroms total diameter and 20-24 angstroms core diameter) and polyallylamine hydrochloride, PAH, have been layer-by-layer self-assembled onto precoated (by poly(diallyldimethylammonium chloride), PDDA, or PAH) substrates. The ultrathin S-PDDA(capped-TiO₂/PAH)_n (n = 5, 10, 15) films have been characterized by absorption and surface plasmon spectroscopies, cyclic voltammetry, and scanning force microscopy. A S-PDDA(capped-TiO₂/PAH)₁₀ film coated by a layer of gold has been shown to function as a Schottky diode.
