Content

This course uses X-ray Diffraction (XRD) techniques to investigate the structural properties of coatings obtained by different deposition methods. Understanding the structure of thin films will improve their fabrication. After introducing basic thin film theory and thin film XRD characterisation methods, fundamental theory and limitations will be discussed including examples of films in applications and how their structures influence characteristics.

The structural properties of the coatings obtained at different substrate temperatures for different chemical compositions will be discussed by X-Ray Diffraction (XRD) techniques. The composition of the layers could also be studied by RBS. The complementarily will be discussed. The understanding of the structure will result in an improved thin film production and fabrication.

Today, coatings are used in many applications for functional or / and decorative purposes. In functional coatings, the surface properties of the substrates such as adhesion, corrosion or wear resistance can be changed. In semiconductor device fabrication, the coating adds completely new properties such as electrical conductivity, magnetic or optical responds.
