Alberto Franceschetti - Senior Scientist
Alberto Franceschetti received his Ph.D. in Condensed Matter Physics from SISSA in Trieste, Italy, in 1994. He then joined the Solid State Theory Group at NREL as a postdoc, 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, to semiconductor/insulator interfaces. In 2004 he returned to NREL as a senior scientist. Currently his main research interests are in the area of semicondutor nanostructures and materials design from first principles.
