Physics Senior Presentation: "Multiple Band Gaps in a Complex Oxide System"

Wednesday, June 5, 2013

12:00 PM-1:00 PM

Physics Major: Marc Doyle

Abstract: Density Functional Theory (DFT) has predicted multiple narrow band gaps in a Strontium Scandium Bismate and Lead Scandium Niobate solid solution. This alloy is predicted to be a ferroelectric semiconductor with at least four intermediate bad gaps in the UV-Visible range. Photoluminescent measurements are used to probe these band gaps and are done by laser excited florescence.
