Dr George Adamopoulos

Senior Lecturer

Research Overview

George Adamopoulos obtained his Ph.D., from Cambridge University (Engineering department) and M.Sci. in Physics from the Aristotle University of Thessaloniki, Greece. After the completion of his Ph.D. he joined a series of academic departments including Ecole Polytechnique (Palaiseau, France), CRNS, Université Louis Pasteur (Strasbourg, France), Advanced Technology Institute, Surrey University (UK), Queen Mary University of London and Imperial College London working on electronic materials, mastering a wide range of thin films deposition and characterisation techniques.

His research interests include (but not limited to) the physics and engineering of a wide range of semiconducting thin films such as carbon-based materials, metal oxides and organic semiconductors. The last few years he is focused in the deposition and characterisation, doping mechanisms, defects and interfaces of solution processed metal oxide-based conductors, dielectrics, semiconductors and CIGS for high performance thin film transistors and their applications in touch panel displays, AMOLEDs and optoelectronic devices.
