Groupe Photemission, Photodiffraction et Spectromicroscopie

The group's research activities focus on the analysis of electronic structure and the chemistry of surfaces and interfaces using spectroscopic and diffraction techniques of photoelectrons.

Contact: N. Barrett

Members of the laboratory.



Nanostructured surfaces constitute substrates very interesting for the deposition of thin layers, because one can hope that this substrate nanostructuration will be transmitted to the deposited layer. A nanostructuration at an atomic scale can be obtained by heat treatments adapted under controlled atmosphere, by interaction with a laser, or by homoepitaxy (i.e. by the deposition of a material identical to the substrate).

Groupe SIMA

Les activités de recherche du groupe SIMA portent sur le contrôle atomique des surfaces, interfaces et nanostructures, les propriétés électroniques, structurales, la croissance de films, les processus élémentaires aux surfaces et interfaces.
