Nikolaos Georgoulas

Professor, Laboratory Director

Nikolaos Georgoulas received the diploma degree in Electrical and Computer Engineering (Dipl.-Ing.) from the department of Electrical and Computer Engineering, Technical University of Munich (TUM), Germany, in 1978 and the PhD Degree (Dr.-Ing) from the same department in 1981. Since 1985, he is a faculty member of the department of Electrical and Computer Engineering in the Polytechnic School of the Democritus University of Thrace (DUTh). His scientific interests are mainly focused in Microelectronic and Nanoelectronic technology. In these areas he has published more than 65 papers in international scientific peer reviewed journals and conferences and has participated in more than 18 research and development projects. Since 2008 he is the Director of the Laboratory of Electrical and Electronic Materials Technology (former name of Micro and Nano-Technology Laboratory). Prof. Georgoulas served as the Head of Electrical and Computer Engineering Department for two consecutive terms (1997-1999 and 1999-2001), as member of the Deanship (1997-2001), as member of the Senate (1997-2001) and as member of the Research Committee of DUTh (1997-2003).
He specializes in:

  • Microelectronics and Nanoelectronics Technology
  • Optoelectronics Technology
  • Microsensors Technology
  • Photovoltaic Technologies
  • Energy storage Technology (Li-ion batteries)
  • Technological Process and Microelectronic Devices Simulation

See a selection of his journal and conference articles, PhD dissertations, MSc theses and diploma theses.

Filippos Farmakis

Assistant Professor

Dr Filippos Farmakis received his B.S. degree in Physics from Aristotle University of Thessaloniki, Greece, in 1996, the MSc degree in Optics, Optoelectronics and Microwaves from National Polytechnic School of Grenoble, France, in 1997 and his PhD from the same School in 2000. His dissertation was on the electrical and noise characterization as well as reliability aspects in polycrystalline silicon thin-film transistors. After earning the PhD degree, he joined UNAXIS SA, Palaiseau, France as Process Engineer and later as R&D Team Leader where he worked on thin film deposition on PECVD production systems for the display industry. In 2006 he pursued his research on chemical sensing field-effects devices and thin film transistors with IMEL, NCSR Demokritos, Athens, Greece, after receiving a grant from a project co-financed with the European Union. In 2008, he was employed as the Head of Technology at Heliosphera SA, a Greek company producing thin film photovoltaic modules in a 60MW manufacturing line. From January 2012, he is Lecturer and from July 2015 Assistant Professor at Democritus University of Thrace, Electrical and Computer Engineering Department in Xanthi. He is the author and co-author of more than 50 scientific papers in refereed international journals and conferences.
He specializes in:

  • Solar cell technology
  • Thin films
  • Lithium- ion battery cells
