Today, coatings are used in many applications for decorative or / and functional 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 responses. This course uses X-ray Diffraction techniques (XRD) 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 and HR-XRD characterisation methods, fundamental theory and limitations will be discussed including examples of films in applications and how their structures influence characteristics.
Real samples will be measured. In-house protocols will be presented for establishing reproducible and reliable measurements, and for interpreting stress/strain and materials defect levels.
- Introduction to different X-Ray techniques
- Relationships between physical and structural properties
- High resolution X-Ray techniques
- Coherent and non-coherent scattering
- Texture and stress
- Coatings case studies
- Examples of successful technology transfers using X-ray techniques

Alex Dommann obtained his Ph.D. at ETH Zurich after graduating in solid-state physics and crystallography at the University of Zurich.
He was a research fellow at the California Institute of Technology, a research scientist at the Paul Scherrer Institute and at ETH Zurich’s Laboratorium für Festkörperphysik. In 1991, he was appointed Professor of materials research at the Interstate University of Applied Sciences Buchs, where he was Scientific Head of the Institute for Microsystems from 1997—2004. In 2005 he was appointed CTO of the CSEM, Centre Suisse d’Electronique et de Microtechnique at Neuchâtel. In July 2013 he was appointed Head of Department “Materials meet Life” at Empa, Swiss Federal Laboratories for Materials Science and Technology. His research concentrates on the structuring, coating and characterization of thin films, MEMS and bio-interfaces. He made significant contributions to all aspects of thin films characterization and aging of MEMS. More than 10 years of experience in space projects. His studies led to a variety of new semiconductor structuring and coating processes. His contributions have opened up exciting possibilities for future research in the area of semiconductor and MEMS structuring, thin films and Bio-coatings.
He is a member of different national and international technical and scientific committees.
Antonia Neels studied chemistry at the Humboldt University of Berlin (D) and obtained a PhD from the University of Neuchâtel (CH). After a postdoctoral position at the Texas A & M University she has been appointed Maître Assistant at the University of Neuchâtel in 1997. She has been leading the XRD laboratory at the IMT EPFL and CSEM from 2006 until 2014. In 2014, she graduated from the EPFL / HEC Lausanne and received an Executive MBA in Management of Technology MoT. Since July 2014, she heads the Center for X-ray Analytics at Empa, Swiss Federal Laboratories for Materials Science and Technology (http://www.empa.ch/x-ray).
Her interests are focused on new materials, their fascinating structures leading to new physical properties and applications. She is experienced in the development and application of X-ray based analytical methods and as a part of Empa’s department ‘Materials meet Life’ she focusses her X-ray analytical research towards bio-medical questions.
Since 2018, Antonia Neels is appointed Titular Professor at the Faculty of Mathematics, Science and Medicine at the University of Fribourg. She gives courses related to ‘Applied Crystallography’ at different Swiss universities and has published more than 240 academic research papers.
Ruggero Frison graduated in Physics at the University of Padua (I) and obtained his Ph.D. at ETH Zurich. He was a post-doctoral researcher at the Institute of Crystallography-CNR, Italy and at the University of Zurich, Switzerland. Later he worked as Physicist at Excelsus Structural Solutions (Swiss AG). Since 2018 he has been a scientist at the Center for X-ray Analytics at Empa, Swiss Federal Laboratories for Materials Science and Technology (http://www.empa.ch/x-ray).
His research interests are on structural dynamics, disorder and physical properties of materials. As the functional properties of many materials depend strongly on the presence of correlated defects within their structure, the use of k-space probes such as X-ray diffraction and scattering techniques provide essential information about short-range order in crystalline lattices, systems in between order and disorder and amorphous materials.
The final goal is to find and understand the organizing principles that govern physical properties in the presence of complex disorder, which is a first step toward the design of novel materials for different kinds of applications, from sensors for new medical technologies to information- or energy-storage.
