Dr. Konstantinos P. Giannakopoulos CPhys is a Researcher of INN, expert in nanostructural materials characterisation; he is a Physicist (1995, Aristotle University of Thessaloniki) with a PhD (1998, Engineering, University of Liverpool) on the study of heteroepitaxial growth of III-V semiconductors on vicinal substrates. He has worked in ST Microelectronics (Advanced R&D, Crolles, France) on the characterization of selectively grown heteroeptiaxial thin films and on the evaluation of industrial equipment for this task. Since 2002 he works in NCSR Demokritos on the growth and structural characterization (esp. with Electron Microscopy) of a large variety of nanomaterials and nanostructures. The techniques that he is currently involved in are: High Resolution Transmission Electron Microscopy (HR-TEM)- combined with Energy Dispersive X-ray Spectroscopy (EDS), Field Emission Scanning Electron Microscopy (FE-SEM)-combined with low voltage imaging and energy filtering of secondary electrons, various Scanning Probe Microscopy techniques (AFM, Conducting AFM), Physical Vapour Deposition (PVD, incl. Electron-beam physical vapor and sputter deposition). He has worked on a large variety of Advanced Materials that include: oxides (eg for applications in self cleaning surfaces), semiconductors (e.g. for applications in gas sensors), metallic nanoparticles for applications in nanoelectronics (for advanced non-volatile memories and magnetic recording media), nanoparticles generated in aerosols . He has taught in the University of Liverpool, the National Technical University of Athens, the University of Novi Sad, Serbia (Honorary Professor) etc. He has also worked at Mantis Deposition Ltd (UK), the University of Cyprus and he has been an Expert Evaluator of funding proposals for the EU and other funding bodies. Ηis team was among the winners of the EUvsVirus competition (https://covid-eic.easme-web.eu/solution/sers-substrates-virus-detection-exhaled-droplets/about). Ηe sub-coordinated an EU project for the promotion of the field of Advanced Materials to the European public (www.materialsfuture.eu) and he coordinated an ERANET project on self cleaning mirrors (https://nano4csp.cyi.ac.cy). He has co-organised 19 National and International Conferences (incl EUROMAT 2017), and he is the co-author of 110 peer-reviewed scientific publications in scientific Journals (84) and Conference Proceedings; he has received more than 1660 references for his work (h-index 24).
