Chemical bath deposition and electrodeposition of epitaxial semiconductor materials for application in photovoltaic devices

"This dissertation investigates the chemical bath deposition of zinc oxide and electrodeposition of cuprous iodide on polycrystalline and single crystal substrates. Paper I describes the chemical bath deposition and characterization of titled epitaxial zinc oxide nanospears on Si(001) single crystal substrate. In Paper II, the chemical bath deposition of zinc oxide nanospears from highly alkaline solutions is discussed in detail, including a thermodynamic calculation of saturation and speciation of Zn(II) in aqueous solution, and a kinetic study of the deposition process. In this paper the epitaxial zinc oxide is reported grown on Au(100), (110), and (111) single crystals. Paper III involves the electrodeposition of epitaxial cuprous iodide thin films on single crystalline Au(100) substrate from a slightly acidic Cu(II)-EDTA-KI solution. The electronic property of the so deposited CuI film is estimated by photoluminescence spectroscopy. This dissertation also includes three appendices. The first two appendices cover the supplementary materials for Papers I and II. The third appendix has unpublished results on thermal transformation of electrodeposited magnetite and ferrihydrite into hematite"--Abstract, page iv.
