The Leibniz-Institute for Crystal Growth (IKZ) is a leading research institution in the area of
science & technology as well as service & transfer of crystalline materials. Our goal is to enable solutions for urgent societal challenges (e.g. communication, artificial intelligence, climate protection, health etc.) by modern electronic & photonic technologies. The work covers the full spectrum from basic over applied research up to pre-industrial development and is performed in collaboration with national and international partners from university, academy and industry. The institute is part of Forschungsverbund Berlin ( and a member of the
Leibniz Association You can find more details on the institute webpage:


We are offering a

PhD Student Position (m/f/d)

for the topic:

Investigation of Polarization Switching Kinetics in Ferroelectric/Dielectric Thin Films

At the Leibniz-Institute for Crystal Growth, ferroelectric oxide layers are epitaxially grown by metal-organic chemical vapor phase epitaxy (MOVPE). In these thin films, the switching of the ferroelectric polarisation is a fundamental phenomenon, which enables a multitude of technological applications. However, the underlying switching processes are often not yet fully understood. In the present project, the kinetics of the polarisation switching shall be investigated in more detail by correlated operando studies in which X-ray diffraction is performed simultaneously with electrical measurements. These investigations are intended to reveal the correlation of electrical properties, switching behaviour and local structural properties of domains and domain walls in a complex material system. The planned works are embedded in a joint DFG project (FeDiBiS) together with our partner NaMLab (Dresden).

The tasks of the PhD student will include the epitaxial growth of the thin films and their structural/ferroelectric characterization by state-of-the-art synchrotron radiation X-ray techniques and piezoresponse force microscopy.


Applicants must hold a master degree either in physics, chemistry, materials science or related fields with relevant experience

  • Skills in these fields are welcome: materials science, epitaxy, x-ray diffraction, piezo-/ferroelectricity, synchrotron radiation, programming (e.g. Python)
  • You enjoy working in a motivated team
  • Good English language skills written and oral
