Séminaire Upgrade - Complex intermetallic compounds: from surface structures to surface properties

8 juillet 2019 14h • Amphithéâtre de SOLEIL


(Directrice Scientifique, MINES Nancy, Campus Artem, Nancy, France)


Complex intermetallic compounds are a class of ordered alloys consisting of quasicrystals and periodic crystals with large unit cells.  Their specific structures, which are best described by a stacking of highly symmetric polyhedra and/or a network of bonds with a covalent-like character, are responsible for unusual surface properties – at least when compared to those of conventional alloys. Complex intermetallic compounds surfaces are then currently considered for a number of applications, such as efficient coatings, as templates for building new molecular nano-structures oras novel catalytic materials. The detailed knowledge of the surface structure is a necessary step for further studies of surface properties. In this talk, I will show that the combination of experimental and theoretical methods isextremely useful to determine the surface structures, as well as to unveil how the surface properties are controlled by their geometric and electronic structures.
