Wide Band Gap Semiconductor Nanowires 1

Vincent Consonni is Associate Scientist at CNRS (French National Center for Research) in France. His research has focused on the physics of crystal growth and of condensed matter for micro- and nano-structures involving compound semiconductors such as CdTe, GaN, ZnO and SnO2. He is currently working on transparent conductive materials and ZnO nanowire-based solar cells. He has published approximately 30 articles in peer-reviewed journals. Guy Feuillet is Senior Scientist at CEA (French Atomic and Alternative Energy Commission), France. He has initiated and coordinated many internal programs (GaN nanostructures, X-ray detectors for medical imaging, solid state lighting) and R&D programs during his work at CEA. He is a permanent member of the scientific advisory board at CEA/LETI, and a member of the selection committee for the French National Agency for Research (ANR). He has published about 120 papers in peer-reviewed journals.
