Description

Opportunities exist in basic and applied research to study plasmonic/dielectric composite nanostructures, which generate unique optical, chemical, and physical properties. Ultimately, these properties will be explored as a means of enhancing adsorption, detection, catalysis, and energy conversion. This project will entail the computational design and synthesis of composite nanoparticles and composite arrays. This work focuses on a systematic understanding of the coupling of multiple resonances with a given nano-architecture, which will serve as a means of designing composites for specific applications. Much of this work will entail the fabrication of multilayered nanoparticles using wet chemistry techniques, although lithographic techniques may also be explored as a means of fabricating multilayered stacks/arrays. Familiarity with computational electromagnetics is a plus and will guide the synthesis portion of this project (i.e. finite difference time domain [FDTD]) finite element method, rigorous coupled wave theory.
