"Single-crystal Si is the bedrock of semiconductor devices due to the high crystalline perfection which minimizes electron-hole recombination, and the dense native silicon oxide which minimizes surface states. To expand the palette of electronic materials beyond planar Si, an inexpensive source of highly ordered material is needed that can serve as an inert substrate for the epitaxial growth of grain boundary-free semiconductors, photonic materials, and superconductors. There is also a need for a simple, inexpensive, and scalable fabrication technique for the growth of semiconductor nanostructures and thin films. This dissertation focuses on the fabrication of semiconducting nanowires (polycrystalline Ge & …

"Electrochemical deposition methods are presented for the deposition of Co(OH)2 and Cu metal. Paper I shows the deposition of β-Co(OH)2 on Ti through electrochemical reduction of [Co(en)3]3+ to [Co(en)3]2+ in 2M NaOH. The catalytic properties of the deposited Co(OH)2 towards water oxidation is found comparable to Co3O4, with the surface of the Co(OH)2 converting to CoOOH during the reaction. Paper II gives the conditions suitable for epitaxial growth of Co(OH)2 on Au(100), Au(110), and Au(111) following the same reduction mechanism as described in Paper I. …
