Dr. Deligeorgis George
Principal Researcher

Dr. George Deligeorgis earned his PhD in 2008 working on GaAs based Semiconductor laser diodes for telecommunication applications. Following his PhD, carbon-based devices (Graphene and CNTs) became his principal research interest. He stayed in LAAS-CNRS (Laboratory for analysis and architecture of Systems, National Center of Scientific Research), in France between 2010-2014 where he continued his activity in the same subject. He is a Researcher in FORTH - IESL since (2015) working on high frequency carbon and 2D based devices.

Dr. Deligeorgis has worked on numerous projects in design and fabrication of compound semiconductor devices in the field of photonics and high frequency electronics (MMIC) for the last decade. He was involved in several National and European funded projects in the fields of photonics, RF device fabrication and polaritonic devices. He is currently leading the 2 dimensional material based electronics activity in the microelectornics research group, while working on nonlinear graphene based RF devices and polariton optoelectronics devices combining his knowledge in physics and nanotechnology. He has published more than 60 articles in peer-reviewed journals and has several invited and contributed talks. Finally, Dr. Deligeorgis is a founding member of the “Graphene Center, Greece”, member of the Steering board of Micro & Nano nanotechnology company, a member of several associations (IEEE e.t.c) and a reviewer in several international journals
