Surfaces and Interfaces

Beamline BM32 (see website)

The IF (InterFaces) beamline is dedicated to structural and applied studies in nanoscience and technologies  using the synchrotron radiation.

Materials can be studies ex situ or in situ (under high ultra vacuum, or controlled atmosphere, in air) during their elaboration & working processes or under various loadings (e.g.: thermal, mechanical, electrical).

3 INSTRUMENTS

Ultra-vacuum in situ nanostructures studies instrument

> Atomic structure, morphology and composition.
> Nano-structures : islands, particles, nanowires, graphene, 2D materials.
> Surfaces-interfaces : alloys, heterostructures, catalyse.
