ABOUT/BIOGRAPHY

Dr. Dimitrios Velessiotis holds a B.Sc. in Physics from Patras University since 1997 and a 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 the fabrication by means of electron beam lithography (EBL) of molecular junctions based on mixtures of polyoxometalate acids and lithographic resists and their consecutive electrical characterization. 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. From 2013 onwards, he continued working on various INN’s research projects and activities, focusing on structural and electrical characterization of several materials used in electronic devices by means of SPM and the fabrication (using EBL) and electrical characterization of nano-wire (NW) transistors. Currently, Dr. Velessiotis is coordinator of an HFRI project titled “Low-Cost Carbon Nanotubes Photodetectors” (project’s site: http://carbonphotodetectors.eu). His research interests include electron beam lithography and its applications, molecular electronics devices carbon nanotubes photodetectors and scanning probe microscopy. He is coauthor in 20 papers in international scientific journals with approximately 260 citations and h-index = 9. He has also participated in 28 announcements in national and international conferences (including 3 invited talks) and in 1 patent
