Job description:

Your Job:

This master’s thesis aims to produce freestanding SrTiO₃ films with a thickness of less than 100 nm using various established remote epitaxy methods. The efficiency of these methods will be evaluated by characterizing the film’s microstructure at atomic resolution using advanced transmission electron microscopy (TEM) techniques. The experiments will be conducted at ER-C-1 and the cleanroom of HNF FZJ, in collaboration with PGI-7 and PGI-9 FZJ. These freestanding SrTiO₃ films will serve as electron-beam-transparent membranes (patent pending), designed to be technologically compatible with the epitaxial growth of high-quality superconducting and ferromagnetic oxide films.

Key objectives:

1. Fabrication of electron-transparent freestanding SrTiO₃ films
2. Atomic-scale characterization of their microstructure using TEM
3. Growth and analysis of epitaxial superconducting and ferromagnetic oxide films on the freestanding SrTiO₃ membranes

Your Profile:

• You are studying physics, material sciences, engineering, or a related subject at a university and are looking for a topic for a master’s thesis.
• You are interested in and ideally also have previous knowledge in the fields of electron microscopy and solid state physics.
• You can work independently and responsibly, show commitment, a high level of teamwork, and enjoyment of cooperative collaboration.
• Furthermore, you can quickly familiarize yourself with new methods and techniques.
• You are fluent in written and spoken English.

Our Offer:

We work on highly relevant, innovative topics and offer you the opportunity to actively shape change!

We offer you:

• An interesting and socially relevant topic for your thesis with a future-oriented focus
• Ideal conditions for practical experience alongside your studies
• Interdisciplinary collaboration on projects in an international, committed, and collegial team
• Excellent scientific equipment and the latest technology
• Qualified supervision by scientific colleagues
• Independent preparation and implementation of the assigned tasks
• A large research campus in the countryside, which offers the best opportunities for networking with colleagues and for sporting activities alongside work
• Flexible working hours and appropriate remuneration
• The opportunity to work flexibly (in terms of location), e.g., partly from home

In addition to exciting tasks and a collegial working environment, we offer you much more: go.fzj.de/benefits

We welcome applications from people with diverse backgrounds, e.g., in terms of age, gender, disability, sexual orientation / identity, and social, ethnic, and religious origin. A diverse and inclusive working environment with equal opportunities in which everyone can realize their potential is important to us.
