The Fraunhofer-Institute for Electron Beam and Plasma Technology FEP works on innovative solutions for vacuum coating and the treatment of surfaces, liquids and gases.

The Stationary Precision Coating working group in the field of plasma technology deals with the development of plasma-based vacuum coating processes an technologies for the producation of functional coatings using reactive magnetron sputtering.

We offer a position for a final thesis, starting as soon as possible : Sputter deposition of piezoelectric and ferroelectric AIScN thin films with high Sc content for applications in key components for wireless, optical and quantum communication

What you will do

The main objective of the project is to investigate the feasibility of using magnetron sputtering to grow piezoelectric wurtzite Al(X)Sc(1 -X)N ("AIScN") films on !arge area with high Sc content between (1-x) = 0.3 and 0.5. Current film growth technology achieves

wurtzite growth up to 0.43, but usually as a mix together with cubic.

The work will be comprised of three parts :

1. Gaining deep understanding of sputter process parameter space through literature reviews

2. Plan and implementation of experiments and material characterization to find a way to tailor the process conditions for growth of

wurtzite AIScN with high Sc content

3. Participate in design and fabrication of test structures to evaluate the piezoelectric, dielectric, and other properties of the films.

What you bring to the table

• university study course preferably in Material science, Physics, Electrical Engineering or other related fields;
• strong hands-on and problem-solving skills; high motivation, good organizational skills, and an independent and conscientious approach
• to work;
• reliability and a high degree of initiative; interest in material science as well as interdisciplinary cooperation and good team spirit;
• strong communication skills including good oral and writing skills; very good English skills and at least a basic knowledge of German
• would be preferred;
• previous experience with magnetron sputtering or other PVD methods, structural analysis, characterization of piezoelectric materials are

not a pre-requisite but would be highly appreciated.

What you can expect
