Elton Graugnard's Homepage
Welcome to my website!
I am an assistant professor in the Department of Materials Science & Engineering at Boise State University. My full curriculum vitae can be found in the links at left, but briefly I am currently involved in DNA-based nanotechnology research in collaboration with Bill Knowlton, Bernie Yurke, and Will Hughes in the Nanoscale Materials and Device Group. My contact information at Boise State can be found here.
Previously, in collaboration with Chris Summer's Nanophotonics research group in the School of Materials Science & Engineering at Georgia Tech, I developed techniques to fabricate and manipulate the optical properties of 2D and 3D photonic crystals using atomic layer deposition (ALD). Using ALD systems I designed and built, we developed several successful ALD protocols to grow thin films and multi-layers of titanium dioxide (TiO2), aluminum oxide (Al2O3) and gallium phosphide (GaP) within synthetic opals and 2D slab waveguides. This allowed us to tune and enhance the optical properties of these structures for specific applications.
I've also worked on ultra-high vacuum scanning tunneling microscopy (STM) of semiconductor surfaces (Si and GaAs). I studyied the etching of semiconductors with halogens, atom-by-atom. Some STM images of clean and etched surfaces can be found under the STM link. I also used a variable-temperature STM to study the surface dynamics and evolution in 'real time'.
In graduate school, I worked in Ron Reifenberger's group on the field emission and electronic conductance of multi-walled carbon nanotubes (MWNTs).
