salary: EG 13 TV-L

beginning:

In the Department of Mathematics and Natural Sciences in the Group Fundamentals of Energy Materials at the Technische Universität Ilmenau (Germany) is a vacancy for a

Research assistant (f/m/d)

to promote their own academic qualifications within the meaning of

• 2 (1) of the German Academic Fixed-Term Contract Act (Wissenschaftszeitvertragsgesetz) as soon as possible/ from .

In our group, we are preparing and analysing nanowires (NWs) from III-V semiconductors in various device structures for energy conversion and other high-performance applications. For the NW analysis, we are using various materials science characterization methods including a dedicated 4-tip scanning tunnelling microscope. In this project funded by the German Research Foundation (DFG), we are addressing III-nitride resonant tunnel diodes in NW core-shell structures for improved performance in the THz range together with our project partners at the University Duisburg-Essen. Key challenges are the crystal quality of the heterostructures and internal polarization fields.

Your tasks

Your job tasks includes the following responsibilities:

• Analysis and evaluation of III-V semiconductor structures grown by metal organic chemical vapour deposition (MOCVD), in particular, resonant tunnelling diodes.
• Electrical characterization of the structures using a 4-tip scanning tunnelling microscope and electron beam-induced current measurements with regard to charge carrier transport paths.
• Materials science analysis of nanowire morphology, investigation of the various structural areas, in particular local composition differences, using scanning electron microscopy and energy-dispersive X-ray spectroscopy.
• Technical support for the department in teaching, e.g. topic-relevant theses.
• Publication and presentation of results at national and international conferences and in journals.

Your profile

For being part of the selection process is needed:

• A completed university degree (Master's or Diploma) with above‑average grades in a natural science, materials science, or engineering subject (e.g. physics, chemistry, renewable energy technology, materials science, or electrical engineering).

Following competences are desirable:

• In-depth knowledge of Semiconductor physics mandatory.
• Knowledge of Natural sciences (physics, chemistry), materials science, and/or engineering in semiconductor preparation.
• Ability to work independently and responsibly in an innovative, interdisciplinary team and research environment.
• Language (English B2 level, German B2 level) skills.

Please provide evidence of the qualifications required for the job by certificates and references.

The job is not suitable for part-time employment.

The interviews will be placed in calendar week 14/2026 and 15/2026.

What we offer you

• attractive remuneration according to collective agreement (as per TV-L) incl. granting of a special annual payment
• vacation entitlement of 30 days in the calendar year and additional days off on 24 / 31 December
• family-friendly, flexible working time model
• VBL - pension scheme in the public sector
• wide range of individual training opportunities
• extensive health and sports programs
• respectful working environment at a renowned university
