Dr. Elton Graugnard is an Research Assistant Professor with the Department of Materials Science & Engineering. Prior to joining Boise State, he served as a physics professor at Rollins College involved in photonic crystals research. In collaboration with Chris Summer's Nanophotonics research group in the School of Materials Science & Engineering at Georgia Tech, he developed techniques to fabricate and manipulate the optical properties of 2D and 3D photonic crystals using atomic layer deposition (ALD). Dr. Graugnard has also worked on ultra-high vacuum scanning tunneling microscopy (STM) of semiconductor surfaces (Si and GaAs). Recent professional activities have included publishing several articles in Applied Physics Letters, presenting at ECS Transactions, and membership in the American Physical Society.
