Your Job:

In this Master`s thesis, ternary nitride compound semiconductor samples are to be characterized both electrically and structurally using off-axis electron holography, scanning transmission electron microscopy, convergent electron beam diffraction, and geometrical phase analysis. These experiments will be conducted to understand the carrier dynamics in these mateials system with and without laser beam illumination using directed electron detectors.

Your tasks in detail:

• Preparation of electron transparent TEM specimens
  
• Determination of lamella thicknesses by convergent electron beam diffraction and electron energy loss spectroscopy
  
• Mapping of electrostatic potentials and excited carrier concentrations using off-axis electron holography under laser illumination

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, solid state physics, and laser optics.
  
• You can work independently and reponsibly, 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 topic
  
• 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
