The Leibniz-Institut für Kristallzüchtung (IKZ) is a leading research institution in the area of crystal growth of technologically important materials for micro-, opto- and power electronics, sensors, optics and laser technology. This ranges from explorative fundamental research to pre-industrial development. It is part of Forschungsverbund Berlin e.V. and a member of the Leibniz-Association.


The Leibniz-Institut für Kristallzüchtung is now awarding a


Master Thesis


for the topic


„Phase formation and phase stability in the (AlxGa1-x)2O3 system”


Alloys of (AlxGa1-x)2O3 belong to the material class of transparent semi-conducting oxides and have recently attracted a lot of attention as application for next-generation high power electric devices which are mandatory to successfully realize efficient smart energy grids and electrical vehicles. The basic understanding of formation and stability of different possible crystalline phases during the synthesis and growth of (AlxGa1-x)2O3 compounds is, however, not well understood for this material class yet.

To get insight into this topic, within the Leibniz Science Campus “GraFOx” amorphous as well as crystalline films of (AlxGa1-x)2O3 are deposited and annealed under varying conditions and characterized at the IKZ by a variety of techniques including X-ray diffraction, ex-situ and in-situ transmission electron microscopy (TEM).


The work includes:

  • annealing of amorphous (AlxGa1-x)2O3 films in different atmospheres and temperatures
  • ex-situ TEM and X-ray diffraction studies of as-deposited crystalline films and annealed amorphous       samples
  • in-situ TEM annealing experiments of amorphous (AlxGa1-x)2O3 films to observe the dynamics of formation, transition and stability of crystalline phases
  • creative cooperation in the development and implementation of new data analysis methods based on machine learning


Required are:

  • field of study: Physics, Chemistry, Material Science
  • completed bachelor's degree with the focus on experimental work
  • good English language skills
  • knowledge and experience in X-ray diffraction or TEM are favorable


A combination with an employment as a student assistant up to 8 hours a week à 11,24 € is possible. For further information please contact Dr. Toni Markurt,, Tel.: 030/6392-3066, or Dr. Martin Albrecht,, Tel.: 030/6392-3094.


Severely handicapped persons with equal suitability will be given preferential consideration. There is equal opportunity for female and male applicants. The Leibniz-Institut für Kristallzüchtung actively supports the compatibility of career and family.
