Thin Films, Interfaces and Nanostructures

BACK

The main objective of this internal research program is the development and application of synchrotron techniques to investigate the organization of atoms and molecules at interfaces, thin films, membranes, heterostructures and nanostructures, and to explain exotic electrical, magnetic and catalytic properties emerging from the interaction between location and dimensionality of electrons in these structures.

Although there may be sometimes intersections of the topics covered in this area with, for example, the physical properties of nanoparticles, much of the practical applications of these systems is in the microelectronics industry, relatively far from the innovation chain of the national industrial park. Still, the progress made in this program have an impact on the global knowledge frontier of condensed matter at its most fundamental aspects. This is even an area of major national scientific production, experimental and theoretical, and that motivates the development of innovative experimental methods with the use of synchrotron light, which ultimately have an effect on many other areas.

In the UVX synchrotron light source, the beamlines PGM, SGM and XRD2 are the main experimental stations where projects in this subprogram are currently run. The first two for their ability to observe electronic properties by ARPES, PEEM and XMCD techniques; and the latter for its ability to measure the atomic organization of surfaces and interfaces by GID, GISAXS and reflectivity techniques.
