Abstract

"The current primary methods for epitaxial growth are energy intensive, requiring high temperature or high vacuum to obtain quality thin films. This dissertation explores the solution process methods of electrodeposition and spin coating for growth of epitaxial thin films. First, a method is developed to directly electrodeposit epitaxial CH3NH3PbI3 perovskite for solar cells on single crystal Au by electrochemically reducing I2 in organic solution. Perovskite is a newly explored material for solar cells, and its efficiency may be further improved by increasing the crystalline order. Second, a study on epitaxially electrodeposited chiral metal surfaces is presented, including Au films on Si(643) and Si(6̅4̅3̅), and Pt, Ni, Cu, and Ag films on top of Au. Enantioselective oxidation of L- and D-glucose on Ag/Au/Si(643) and Ag/Au/Si(6̅4̅3̅) confirms the presence of chiral surfaces on electrodeposited thin films. This provides an alternative pathway to obtain chiral metal surfaces instead of using expensive single crystal metals. Finally, a new scheme is proposed for spin coating epitaxial thin films. A diverse array of materials are epitaxially spin coated including CsPbBr3, PbI2, ZnO, and NaCl, indicating the versatility of spin coating for growth of high quality films. The potential and future of epitaxial spin coating are further discussed"--Abstract, page iv.
