Nanoscale Electronics and Optoelectronics

Research by Dr. Daniel Santavicca

UNF on nano

We study solid state systems with one or more dimensions on the nanometer scale. These systems provide a testbed for the study of physics in lower dimensions and can display behavior that is strikingly different from macroscopic systems. We are also interested in developing new electronic and optoelectronic devices that exploit the unique properties of nanoscale systems. This work is currently supported by grants from the National Science Foundation (NSF) through the Electronics, Photonics, and Magnetic Devices (EPMD) Program and the Major Research Instrumentation (MRI) Program. Previous grant support came from the NSF EPMD Program, the NSF CMMI Nanomanufacturing Program, a Cottrell College Science Award from Research Corporation, and the NASA-Florida Space Grant Consortium.
