Abstract

"This dissertation presents an investigation of the electrodeposition of metal oxide films and superlattices on conducting polycrystalline and single crystal substrates. In the first part of the study, electrodeposition of magnetite (Fe₃O₄) films and superlattices in the magnetite/zinc ferrite system which exhibit resistance switching is studied. Paper I reports the electrodeposition of superlattices in the magnetite/zinc ferrite system and shows that only superlattices exhibit multistate resistance switching. In paper II, simple polycrystalline magnetite films electrodeposited on stainless steel crystals exhibit multistate resistance switching which can be tuned by controlling the composition of the films. Paper II describes the epitaxial electrodeposition of Fe₃O₄ films on Ni(111) substrates.

In the second part, electrodeposited epitaxial films of CuO onto achiral Cu single crystals using chiral precursors are studied. Paper IV describes chiral electrodeposition of CuO from copper(II) complexes of malic acid on Cu single crystals. X-ray pole figures in conjunction with stereographic projections are used to determine the absolute configuration of the films. X-ray crystal structures of copper(II) malate crystals are analyzed to understand the mechanisms of chiral electrodeposition"--Abstract, page iv.
