Dr. Ray Duffy is a Principal Researcher in Tyndall National Institute, University College Cork, and a fellow in the School of Engineering and Architecture, University College Cork. Dr. Duffy’s research explores emerging materials and devices for future nanoelectronic, Quantum, and ICT applications, and aims to strike a balance between basic science (material properties) and impact (device functionality), while incorporating aspects of theory and modelling in order to gain insight.

Dr. Duffy supervises and mentors postdoctoral researchers, PhD candidates, and Masters students, and has lectured in the undergraduate programme at the Department of Electrical and Electronic Engineering at University College Cork.

He is a Principal Investigator (PI) on the Transition Metal Dichalcogenides (TMD) device activities in the Chips Joint Undertaking NanoIC pilot line co-funded by the European Commission, and lead-PI on the Research Ireland Frontiers for the Future Award “Pulsed laser annealing of low temperature 2D semiconductors for large area applications in electronics using flexible substrates” (21/FFP-A/9897). He is also currently a PI on the EPSRC – Research Ireland Joint Funding of Research Programme “Developing a Quantum Bus for germanium hole-based spin qubits on silicon” (23/EPSRC/3887).

He has a h-index=27 (Scopus), ~175 research papers, ~20 invited presentations in international conferences across the EU, USA, and Asia.

In the past number of years he has been PI, co-PI, or named Collaborator on Science Foundation Ireland, Enterprise Ireland, and EU H2020 projects, such as “Conformal and non-Destructive doping for gate-all-around nanowire devices” (E.I.-IP-2017-0605), “Investigating Emerging 2D Semiconductor Technologies" (SFI 15/IA/3131), “Silicon Compatible, Direct Band-Gap Nanowire Materials For Beyond-CMOS Devices” (SFI 14/IA/2513).

Dr. Duffy has been a major contributor to the EU Horizon2020 ASCENT project (grant agreement 654384) which offers access to research infrastructure and expertise in advanced Nanoelectronics. Based on the successful evaluation of the next phase, ASCENT+, he will be Tyndall’s leader and contact-point for contributions to the Joint Research Activities of the project in 2020-2023.

Dr. Duffy has been Symposium Organiser for European Material Research Society (E-MRS) Fall 2025 and Fall 2022 Symposium “Group-IV Semiconductor Materials for Nanoelectronics and Cryogenic Electronics”, Spring 2019 Symposium "Advances in silicon-nanoelectronics,-nanostructures and high-efficiency Si-photovoltaics", Fall 2017 Symposium "Integration, metrology and Technology CAD co-development for sub-10nm technology nodes", Spring 2015 Symposium "Nanomaterials and Processes for Advanced Semiconductor CMOS Devices", and Spring 2005 Symposium "Material science and devices issues for future generation Si-based technologies". He has been on the Technical Program Committee for the Ion Implantation Technology conference 2012-2026 (process technology); SISPAD 2018 (modelling), and IEEENANO 2018 (novel electron devices).

Specialties: International experience. Customer oriented research. Links to academia. Dissemination of results in journals and conferences. Mentoring of students.
