The Ceramics group at the Department of Materials and Earth Science at TU Darmstadt focusses on the development of new electroceramics. This international group of about 20 researchers is one among the world-wide leaders in the development of lead-free piezoceramics.
For a DFG-funded PhD student position we are looking for a

PhD Student

starting September 1, 2019, fixed-term contract for three years.

You are motivated and interested in investigating the defect chemistry of the lead-free ferroelectric (K0.5 Na0.5)NbO3 (KNN) to control and optimize its properties.

Your profile:

Essential requirements:

  • Excellent Master degree in Materials science, Chemistry or Physics
  • Strong interest in scientific research and above-average motivation to manage the PhD project
  • Very good knowledge of spoken and written English

Desired skills:

  • Strong academic background in one or more of the following subjects: solid state physics/chemistry, crystallography, functional materials
  • Prior experience or Master thesis in a related topic/field of research
  • Hands-on experience* in one or more of the following topics: synthesis of bulk functional ceramics, complex impedance spectroscopy, basic dielectric and ferroelectric characterization
  • Publications in peer-reviewed journals
  • Demonstrated ability for independent scientific research

* Please list these in your resume, only if you are directly involved in the experimentation. Assistance from a technician / assistant does not count as hands-on experience.

Your tasks:

The project involves experimental work and you will be responsible for the synthesis of the materials, detailed electrical analysis involving impedance spectroscopy and oxygen partial pressure dependent investigations, characterization of microstructure using scanning electron microscopy and advanced electromechanical characterization. In addition, you will also work in close collaboration with leading research groups (at TU Darmstadt and abroad) on modelling and synthesis of functional materials.

We are a multi-cultural work group that includes experts in material processing, new material development, mechanical properties of ceramics, defect chemistry and in-situ diffraction.

Opportunity for further qualification (doctoral dissertation) is given. The fulfillment of the duties likewise enables the scientific qualifications of the candidate.

The Technische Universität Darmstadt intends to increase the number of female employees and encourages female candidates to apply. In case of equal qualifications applicants with a degree of disability of at least 50 or equal will be given preference. Wages and salaries are according to the collective agreements on salary scales, which apply to the Technische Universität Darmstadt (TV-TU Darmstadt). Part-time employment is generally possible.

Applications should include a detailed resume that also mentions subjects you have studied in the Master course with grades obtained and list of publications (if any) in peer-reviewed journals. Send applications including Code No. to

Code No. 322
