About/Biography
Dr. Dimitrios Velessiotis holds a B.Sc. of Physics from Patras University since 1997, an M.Sc. in Microelectronics from National and Kapodistrian University of Athens since 2002. He became Dr. of the Informatics and Telecommunications Faculty of National and Kapodistrian University of Athens in 2006. His Ph.D. thesis was titled "Construction of Microelectronic Nanostructures and Nanodevices Using Polyoxometalates" and dealt with fabrication by means of electron beam lithography (EBL) of molecular junctions based on mixtures of polyoxometalate acids and lithographic resists. The experimental work of his thesis was performed in the -then- Institute of Microelectronics (IMEL-now part of INN) of NCSR "Demokritos". Dr. Velessiotis continued working at IMEL first as collaborating researcher at TASNANO EU project (2007-2008), then as post-doctoral fellow (2009-2012) studying self-assembled mono- and multi-layers of polyoxometallates by means of scanning probe microscopy (SPM) as well as using them in the fabrication of molecular electronic devices of the Metal-molecular-Metal junctions’ type. In recent years, he focused on structural and electrical characterization of surfaces using SPM and the fabrication (using EBL) and electrical characterization of nano-wire (NW) transistors. He is coauthor in 16 papers in international scientific journals approximately 230 citations and h-index = 10. He has also participated in 25 announcements in national and international conferences (including 2 invited talks) and in 1 patent.
