Guy Le Lay, winner of the IUVSTA Prize for Science 2025, will present his work at a seminar on July 4, 2025 in Marseille.

Professor Guy Le Lay, Emeritus Professor at Aix-Marseille University and member of the PIIM laboratory (AMU-CNRS research unit), has just been awarded the International Union for Vacuum Science, Technology and Applications (IUVSTA Prize for Science 2025). The prize recognizes outstanding contributions to experimental and theoretical research in the field of vacuum science and applications. It has been awarded every three years since 1998, and Guy Le Lay is the third French winner, after Albert Fert in 2007 and Jean-Marie Dubois in 2016.

The work rewarded by the IUVSTA consists of outstanding achievements in the field of surface physics, more specifically in the study of the formation of metal-semiconductor interfaces controlled on the atomic scale and characterized using the most advanced tools, as well as the particularly innovative achievements of silicene, germanene and other low-dimensional artificial materials known as Xenes, whose properties open up a new horizon of discovery.

Guy Le Lay was previously awarded the Fernand Holweck Prize and Medal in 2021 by the Institute Of Physics and the Société Française de Physique, in recognition of his pioneering role in the study of new two-dimensional allotropes of silicon, germanium, tin and lead.

The award ceremony will take place at the International Vacuum Congress (IVC-23) in Sydney, Australia, from September 15 to 19, 2025. On this occasion, Guy Le Lay will have the opportunity to present his research in an honorary lecture, and to highlight the impact of his ongoing activities over the last ten years on the international scientific community.

As a prelude to this event, Guy Le Lay will present a seminar entitled “Beyond Graphene, from Silicene to Xenes and Majorana fermions: Physics and Major Applications”. It will take place at the Faculté des Sciences site St Charles at 2pm in the Lavoisier amphitheater.

Our warmest congratulations to our eminent colleague.

Two new research leaders at the PIIM lab !

The Habilitations to Supervise Research is the highest diploma in the French academic system. This diploma is necessary to supervise doctoral students.

Eric Salomon subject was about the use of electron spectroscopy to characterise two-dimensional architectures.

Marco Minissale subject was about Laser-based methods to study fusion-relevant materials and their interaction with diluted media

Congratulations to both of them !
The PS team is now the only team in the laboratory whose members all have an HDR!

17ème International Workshop on Hydrogen Isotopes in Fusion Reactor Materials (HWS 2024)

HWS 2024

Sixty scientists from thirteen different countries gathered in the heart of the French Alps to share their latest developments in the understanding the interaction between hydrogen isotopes and materials, a necessity for the use of nuclear fusion as a sustainable energy source.

Forty oral presentations and fifteen poster presentations were given during the workshop, covering a large spectrum from hydrogen recycling in materials, tritium removal technics to the influence of neutron damage on hydrogen retention in materials. The PIIM laboratory was very well represented, with oral presentations by Aleksandr Afonin, Yosvany Silva-Solís, Matthieu Latournerie and Federica Pappalardo, and two poster presentations by José-David Cremé and Julien Denis.

The PATP, Plasma-Surface and administrative teams of the laboratory were involved in the organisation of the event. The event was supported by the CNRS, Aix-Marseille University, the CEA, the Société Française de Physique, the Fr FCM federation and the ISFIN institut.
