Dr. Athanasios Dimoulas is Research Director at NCSR-DEMOKRITOS, Athens, Greece, founder and head of Epitaxy and Surface Science Lab of INN since 1999. Dr. Dimoulas obtained his Ph.D. from the University of Crete and FORTH in Greece in 1991 on MBE heteroepitaxial growth and characterization of GaAs and related compounds on Si and served as post doc and research associate at the University of Groningen CALTECH, University of Maryland at College Park between 1992 and 1999. He has also served as visiting scientist at IBM-Zurich in 2006-2007 and as chair of excellence at CEA Grenoble in 2016-2018. He has participated as PI in 28 EU projects including ERC AdG and PoC grants and has coordinated 8 large collaborative projects on advanced CMOS and Ferroelectric memories as well as beyond CMOS technologies based on 2D materials. He is currently involved in 4 projects on ferroelectric synapses for neuromorphic computing. Dr. Dimoulas has (co)authored 227 technical presentations in refereed journals, with h –index 47. He is included in the 2023 and 2024 Stanford list of top 2% scientists in their field based on c-score.
In FIXIT, Dr. Dimoulas will develop epitaxial FTJ devices on Silicon and BEOL compatible ferroelectric/oxide semiconductor memristor synapses. The main effort is to scale the devices to sub-100 nm dimensions by e-beam lithography to study the switching characteristics. In addition, he will collaborate with FIXIT partners with the aim to integrate the devices into functional passive cross-bar synaptic arrays.

Dr. Polychronis Tsipas
Device Engineer
NCSR-DEMOKRITOS
Polychronis Tsipas studied physics and obtained his M.Sc. in Microsystems and Nanodevices from the National Technical University of Athens (Greece) in 2005 and his Ph.D. from the National Technical University of Athens in collaboration with the Institute of Material Science of NCSR Demokritos (Greece) in 2009 on the growth and characterization of high-k dielectric thin films on Ge. From 2011 to 2012, he worked as a Post-Doctoral Researcher in the Institute of Microelectronics of NCSR Demokritos on plasma etching and characterization of Si, SiO2 and Si3N4 microstructures and nanostructures for microelectronic and optoelectronic applications. The period 2012-2017 he worked at the MBE laboratory of NCSR Demokritos under the SMARTGATE (Smart Gates for the Green Transistor) EU project on search for novel 2D materials like graphene, silicene, germanene, transition metal dichalcogenides and topological insulators for low-power electronic applications. The period 2017-2019, he worked under the Greek State Scholarships Foundation (IKY) program for the strenghtening of post-doctoral research titled as “Information storage in topological (3D Dirac and Weyl) semimetals for applications in non-volatile memories”. In the period 2019-2023, he worked for the SKYTOP (Skyrmion-Topological insulator and Weyl semimetal technology) EU project on the search for novel 2D ferromagnets and topological materials (topological insulators and Weyl semimetals) for skyrmionic and spintronic applications. Since 2023, he works for the FIXIT (Scaled Ferroelectric X-bars for AI-driven sensors and actuators) EU project on the fabrication of low-power memories based on ferroelectrics for the realization of electronic artificial intelligence systems. He has (co)authored more than 60 scientific publications in international peer-reviewed journals and he has received >2400 citations for his work (h-index: 25).
