"Epitaxial electrodeposition is a simple, low-cost technology to produce highly ordered materials on single-crystal surfaces. This research focuses on the epitaxial electrodeposition of wide bandgap p-type semiconductors and epitaxial Cu thin films via a self-assembled monolayer for energy conversion and flexible electronics. Paper I introduces the epitaxial electrodeposition of hole conducting CuSCN nanorods onto Au (111) surface, and lift-off to produce flexible and transparent foils. Highly ordered CuSCN could serve as an inorganic transport layer in various opto-electronic devices such as perovskite solar cells, LEDs, and transistors. An ordered and transparent CuSCN foil was also produced by epitaxial lift-off following a triiodide etch of the thin Au substrate. Paper II presents a scheme for epitaxial electrodeposition of wide bandgap CuBr on Ag via a AgBr buffer layer. CuBr shows potential for short-wavelength photo-detecting devices. Epitaxial CuBr(111) and Cu (100) are produced on Ag (111) and Ag (100) substrates, respectively. An oriented AgBr buffer layer, formed during the electrodeposition, is found crucial for directing the epitaxial growth of CuBr. Paper III describes a technique for epitaxial electrodeposition of a Cu (111) film on a self-assembled monolayer of the amino acid L-cysteine on Au (111). Direct epitaxial lift-off of the Cu film without etching gives a single-crystal-like Cu (111) foil with a low resistivity and good bending stability. It could be utilized as a low cost, flexible and ordered metal substrate for flexible electronics"--Abstract, p. iv
