X-Ray diffraction multi-techniques (XRD)

 

 

We have the latest diffraction equipment to perform several types of diffraction and reflectometry experiments. These studies allow for the identification of crystal structure, alloy composition, relative orientation of different stacked structures, in a non-destructive way, just as much on thin films and nanometric objects like wires or quantum boxes.
