Short Curriculum Vitae

Nikos Pelekanos obtained his Ph.D in 1991 from Brown University (USA), on the optical properties of two-dimensional II-VI compound semiconductors. After a number of post-doctoral stays in various European labs, including the France Telecom Research Center in Lannion and the Max-Planck Institute in Stuttgart, he joined the Semiconductor Physics Laboratory at CEA-Grenoble from 1995 until 2001. Next, he joined the Microelectronics Research group at FORTH in 2001 and the Materials Science and Technology Department of the University of Crete in 2003. His main research theme is the demonstration of novel semiconductor nanophotonic devices. He has coordinated/participated in numerous European, bilateral and national projects. He has obtained the "Solar Innovation 2010" award for his proposal on third-generation low-dimensional semiconductor solar cells, and more recently a Chair of Excellence LANEF, funded by the French government, for a project entitled “Nanowire Innovative Solar Cells”. He has published about 250 publications (2900 citations, h=28) in refereed journals and conference proceedings and holds 6 technical patents.
