PhD Student (f/m/d) Spatially resolved solid state polymorph conversion in Galliumoxide

Through cutting-edge research in the fields of ENERGY, HEALTH and MATTER, Helmholtz-Zentrum Dresden-Rossendorf (HZDR) solves some of the pressing societal and industrial challenges of our time. Join our 1.400 employees from more than 50 nations at one of our six research sites and help us moving research to the next level!

The Institute for Ion Beam Physics and Materials Research is dedicated to the study of materials and their nanostructures that can be considered for future applications in information technology and are based on electrical, magnetic or optical functionalities.

As part of the Institute, the Ion Beam Center invites applications as PhD Student (f/m/d) Spatially resolved solid state polymorph conversion in Galliumoxide.

The position will be available from 1 September 2022. The employment contract is limited till 30 April 2025.

Project description:

In the framework of an international M-ERA.NET research project with partners in Norway and Finland we are developing a method for the controllable solid state polymorph conversion of gallium oxide assisted by ion irradiation. You will use advanced focused ion beams (FIB) to locally change the crystal structure of ß-GaO. Supported by the HZDR staff, you will use state-of-the-art characterization methods to understand  the  process and the limitations of the approach.

Your tasks:

  • Fabrication of k-GaO nanostructures
  • Characterize the formed structures and interpret the results
  • Find the optimum irradiation conditions and ion species for the tasks
  • Closely collaborate with experimentalists (f/m/d) in Norway and theoreticians (f/m/d) in Finland to advance the understanding of the polymorph conversion
  • Disseminate the results in internal meetings and conferences
  • Publishing the results in appropriate journals

Your profile:

  • Master´s degree in Experimental Physics, Applied Physics or Materials Science
  • Interest in large band gap semiconductors and advanced focused ion beams
  • Experience in conducting experimental work and the ability to work with cutting edge scientific equipment
  • Experience in vacuum technology, charged particle microscopy or ion beam technology would be beneficial
  • Readiness to work with an international team
  • Willingness to travel

Our offer:

  • A vibrant research community in an open, diverse and international work environment
  • Scientific excellence and extensive professional networking opportunities
  • A structured PhD program with a comprehensive range of continuing education and networking opportunities - more information about the PhD program at the HZDR can be found here
  • The employment contract is limited till 30 April 2025
  • Salary and social benefits in accordance with the collective agreement for the public sector (TVöD-Bund) including 30 days of paid holiday leave, company pension scheme (VBL)
  • We support a good work-life balance with the possibility of part-time employment and flexible working hours
  • Numerous company health management offerings
  • An employer subsidy for the VVO job ticket
