Hello. My name is Andy. That is a picture of me to the right. I recently finished my PhD in Materials Science and Engineering at Carnegie Mellon University in Pittsburgh, PA. Before that, I studied Chemistry at New York University. Apart from science, my interests are photography, design, contemporary literature, piano, and knitting. If you ask nicely, I will knit you a sweater or play you a song. You can find examples of my work, research, and creative output through the links to the left.
My doctoral research focused on developing improvements in efficiency of semiconductor water photolysis by exploring interface charge in oxide heterostructures. The effects of electric fields arising from p-n junctions, ferroelectric domains, and polar surface terminations were examined. My research focused on the fabrication and photochemical testing of iron based oxide heterostructures. Specifically, I examined the photochemical activity and growth of epitaxial and polycrystalline hematite Fe2O3 films on single crystal and polycrystalline SrTiO3 substrates. The orientation dependence of bulk and thin film hematite photochemical reactivity was determined. Films were examined using combinatorial substrate epitaxy, the growth and analysis using electron backscatter diffraction of films on polycrystalline substrates. This technique opens many opportunities for wide-ranging epitaxy studies of films supported on more diverse orientations compared to films on single crystal substrates.
My doctoral dissertation, The growth and photochemical activity of hematite films on perovskite substrates (PDF), was successfully defended and submitted to the Dean of the Carnegie Institute of Technology at Carnegie Mellon University in September 2012. My research advisors were Paul A. Salvador and Gregory S. Rohrer, both of the Department of Materials Science and Engineering at Carnegie Mellon. This work represents further understanding of the photochemical behavior of thin film and bulk hematite Fe2O3, a promising candidate for incorporation in solar photochemical water splitting systems.
