Postdoctoral researcher in materials physics

Published 2024-06-17

The research conducted at the Department of Physics and Astronomy encompasses a wide range of physics topics, distributed over nine divisions. The department is located in the Ångström laboratory and employs nearly 400 people, 100 of whom are doctoral students. It offers a broad physics curriculum to undergraduate and graduate students, participation in nationally and internationally leading projects for researchers, and opportunities for partnership with industry and various outreach activities.

The recruiting group in the Materials Physics division within the Department of Physics and Astronomy investigates advanced materials for applications in fusion energy, smart windows, hydrogen storage & nanoelectronics using beams of swift ions to link structure and composition on a true atomistic scale with physical properties and macroscopic functionality. The group also performs fundamental investigations of the interaction of ions in matter to obtain a better understanding of the underlying physics and improved methods. These methods permit to determine concentrations and depth profiles of atoms and molecules in a material with very high accuracy for samples from biological, environmental and technological contexts. They can also be used to tailor material properties such as crystallinity or local chemical composition. A 5 MV tandem accelerator, a 350 kV high current ion implanter and a Low-Energy Ion Scattering System form the experimental platform.

Uppsala University hereby declares a Postdoctoral researcher position, at the Department of Physics and Astronomy, to be open for application. A successful applicant is expected to work in basic and applied research within materials physics. The candidate is expected to employ keV and MeV ion beams as both analytical tool and means for materials modification. One focus area will be the nuclear microprobe system for measurements of the chemical composition with high spatial resolution. Engagement in developing advanced data analysis is expected. Applied research conducted mainly for ultra-thin film systems of relevance in electronics, optics, for hard coatings and in related interdisciplinary projects can be part of the working duties. Taking over responsibilities in collaboration projects with industry is anticipated. Supervision of undergraduate and PhD-student projects can be part of the working duties. The work will be of primarily experimental character.

Duties
The project is focused on experimental studies to link structure and composition in complex material systems to their physical properties as well as macroscopic functionality using ion beams with keV and MeV energies. More specifically, this will include:

  • Experiments to measure structure and composition in complex material systems on the micro- and nanoscale and link it to their physical properties as well as macroscopic functionality.
  • Experiments to better understand the fundamental principles governing ion-solid interaction
  • Synthesis and modification of material systems relevant for the studies named above.
  • Handling and development of large-scale instrumentation for non-destructive materials analysis, in particular using a nuclear microprobe system for high lateral resolution.
  • Handling and analysis of complex experimental data, evaluation and simulation with e.g. Monte-Carlo and Molecular Dynamics approaches.

Requirements
PhD degree in physics or technology or a foreign degree equivalent to a PhD degree in physics or technology. The degree needs to be obtained by the time of the decision of employment. Those who have obtained a PhD degree three years prior to the application deadline are primarily considered for the employment. The starting point of the three-year frame period is the application deadline. Due to special circumstances, the degree may have been obtained earlier. The three-year period can be extended due to circumstances such as sick leave, parental leave, duties in labour unions, etc.

Experience using ion beams with keV or MeV ion energies in fundamental and applied research is required. Well-documented research experience using ion beams and handling ion beam instrumentation for material research, fundamental studies or materials modifications is expected.

It is expected that the successful candidate has the personal capabilities necessary to fully carry out the duties of the appointment.

Additional qualifications
Good knowledge of the interaction between ions and solids is considered an advantage.

About the employment
The employment is a temporary position of least two years according to central collective agreement. Full time position. Starting date as agreed. Placement: Uppsala

About the application
Applications should include a brief description of research interest and past experience, a CV, copies of exams, degrees and grades, a copy of your Master thesis (or a draft thereof) and other relevant documents. The candidates are encouraged to provide letter(s) of recommendation and contact information to reference persons.
