Senior Scientist II
Dr. Franceschetti received his Ph.D. in Condensed Matter Physics from SISSA in Trieste, Italy, in 1994. He then joined the Solid State Theory Team at NREL as a postdoctoral researcher, and later as a research associate, working on the electronic and optical properties of semiconductor alloys, superlattices, and nanostructures. From 2000 to 2004, he was a research associate professor at Vanderbilt University and Oak Ridge National Laboratory, where he worked in collaboration with the electron microscopy group at ORNL on topics ranging from nanocatalysis to superconductor grain boundaries and semiconductor/insulator interfaces. In 2004, he returned to NREL as a senior scientist. Currently his main research interests are in the area of semiconductor nanostructures and materials design from first principles.
