Optoelectronics: Making a Material Difference
Department of Chemical Engineering and Materials Science
University of Southern California
The investigation of novel, micro- and nano-structured materials and devices is of particular interest to the field of optoelectronics. Exploring the relationships among the structure, surface chemistry, and optoelectronic properties of porous and non-porous pure-silica materials can provide insight into tailoring material properties for specific applications. Here, we present two disparate routes for the creation of optoelectronic materials and devices; studying first the suitability of microporous pure-silica zeolites for low dielectric constant thin films, and second the effects of surface chemistry on novel, silica-based, optical biosensors. This work demonstrates how probing the pore architecture and surface chemistry of pure-silicas can yield interesting properties that can be used in optoelectronic applications such as integrated circuits, diagnostics, and biosensors.
About the Speaker
Dr. Heather K. Hunt received her B.S. in Chemical Engineering from Iowa State University (2004), and her M.S. and Ph.D. in Chemical Engineering from the California Institute of Technology (2007, 2009) in the research group of Prof. Mark E. Davis. She was awarded an NSF Graduate Research Fellowship for her doctoral work. Since 2009, she has been a post-doctoral scholar in Prof. Andrea M. Armani's research group in the Mork Family Department of Chemical Engineering and Materials Science at the University of Southern California. She is currently investigating new strategies for adding surface specificity to micro- and nano-structured optical devices as part of her work on single molecule binding kinetics using novel optical resonators as biochemical sensors.
