Internships and jobs




Founded in 2002, this team brings together experimentalists and theoreticians interested in the effects of dimension reduction in oxide materials. Thanks to a joint experience/theory collaboration, the group has developed over the past years a recognized expertise in the science of oxide surfaces (surfaces, thin films, nano-objects). Its activity is based on long-term collaborations with other universities, national and international teams, but also with research centers of large industrial groups (Saint-Gobain and ArcelorMittal). The team develops a limited number of perennial scientific themes: atomic and electronic structure, nature of defects, polarity, reactivity, adhesion, hydroxylation, dissolution/precipitation, metal/oxide interfaces. They are mainly focused on binary oxides in various forms (crystals, thin films, nanopowders), in environments ranging from ultra-high-vacuum to liquids or in contact with metals.

Latest publication: The puzzling isotope-induced quantum phase transition in sodium hydroxide

Anhydrous Sodium Hydroxide (NaOH) has a simple structure, from a few K up to room temperature. In contrast, NaOD shows a structural phase transition at 153 K. This spectacular isotope-induced phase transition has been discovered in 1986 and theoretically explained by our group for the first time, by using fully quantum simulations.

Congratulations to Ramiro Zapata for the “Michel CANTAREL” bourse of the Société Française du Vide (SFV) at PLATHINIUM 2023 and for the prize for the best oral presentation @ C’NANO 2023.


Publication of our work investigating the atomic structure of the Ag/α-Al2O3(0001) interface using X-ray absorption spectroscopy and numerical simulations on nanoscale clusters, revealing size-dependent changes in Ag cluster dimensions and coordination. The study shows that as Ag coverage increases, 2D clusters transition to 3D islands, accompanied by reduced adhesion energy at the Ag/α-Al2O3(0001) interface.
