Foundation for Research & Technology Hellas (FORTH), Greece



FORTH participates in the project with the Microelectronics Research Group (MRG) of its Institute of Electronic Structure and Laser (IESL).

The Institute of Electronic Structure and Laser (IESL) of FORTH at Heraklion, Crete, is an internationally recognized center of excellence in Lasers and Applications, Microelectronics and Devices, Polymer Science and Theoretical and Computational Physics. Its aim is to sustain and advance basic and applied research in carefully selected areas, and also to promote and advance technology in Greece.

The Microelectronics Research Group (MRG) of its Institute of Electronic Structure and Laser (IESL). MRG was founded in 1986 and since then it has evolved into a unique, in Greece, full-scale research facility in compound semiconductor micro/nano-optoelectronics working on III-arsenides, III-nitrides, SiC, carbon electronics, oxides and tellurides . Over the years it has participated into many international projects (FP, ENIAC, NATO) like ESPRIT (Nos. 1270, 2035, 2289, 3086, 5018, 5031, 9500, 21315, 28998), RACE (No. 1027), BRITE/EURAM 5416, NATO Sfp “HP-HF SiC power devices”, NATO Sfp “SICPIN”, a US Army ERO on SiC power devices, “QN laser I”, “QN laser II”, “GaNANO”, “AMICOM”, “ULTRAGAN”, “BONTEC”, “PICMOS”, “MORGAN”, “TARGET”, “NANOTEC”, “SMARTPOWER”, “NANORF”, “MERCURE”, “NANOCOM”, “ARTEMOS”, “CLERMONT”, “ICARUS”, “INDEX”, POLAFLOW” “VISOSURF” and numerous national projects. To exploit its accumulated expertise, the group has launched a microelectronics services activity providing epitaxial wafers, processing and measurement services. The latter two are ISO 9001 certified. In 2005 FORTH was among the winners of the Descartes prize for its work on left handed materials. MRG disseminates its research in high quality journals including Science and Nature. MRG has been working with 1D and 2D material nano – fabrication since 2008 and with conventional semiconductors MMIC since its inauguration in 1986. Among the many technical skills developed is a complete MMIC fabrication platform and component library for GaAs (up to 77GHz) and GaN (up to 15 GHz) integrated microwave circuits. Recently (2015) a component library was created for processing of 2D (graphene) and CNT based electronics. In parallel SiC nanowire high voltage JFETs (2017) have been developed. The 2D / 1D activity has recently been enhanced by a new laboratory including CVD for growth of Carbon (CNT and graphene) and 2D sulfide based materials.

Key personnel:

Dr. George Deligeorgis (male) 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 has recently (2015) accepted an Associate Researcher position in FORTH – IESL, Greece to work on high frequency graphene devices for radar applications. 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 heading the graphene and nanofabrication activity in his group, 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. Dr. Deligeorgis has more than 1300 citation and an h-index of 19.

Prof. Maria Kafesaki (female) is an Associate Professor in the Dept. of Materials Science and Technology of the University of Crete and associated Researcher at the Institute of Electronic Structure and Laser (IESL) of Foundation for Research and Technology Hellas (FORTH).
