Postdoctoral Researcher, Ion Beam Physics

University of Helsinki

Helsinki, Finland

Are you interested in working with ion accelerators in the field of condensed matter physics? Are you looking for an environment that fosters competence and friendly atmosphere in an international academic setting? We welcome you to apply for a Postdoctoral position at the University of Helsinki.

Position description

The postdoctoral researcher will focus on developing ultra-low energy ion implantation technologies for nanomaterials manipulation. They will join the project “Metal atoms on functional nanoplatforms” funded by the Research Council of Finland at the University of Helsinki, and part of the work will be conducted during extended research visits at the Tandem Laboratory in Uppsala University in Sweden.

The project investigates the engineering of 2D nanomaterials by ion implantation. These layered materials act as functional nanoplatforms with versatile use in many fields from quantum optics to nanocatalysis. Traditionally, ion implanters often operate at the keV-MeV energy range, but much lower energies are required for implantation into 2D materials (10-200 eV). The key part of the responsibilities of the postdoctoral researcher is to further develop, test and work with the ultra-high-vacuum instrumentation designed for ion implantation at ultra-low energies.

The employment will be in Helsinki at the Accelerator Laboratory with extended research visits to the Tandem Laboratory at Uppsala University.

Selection criteria

The candidate should have an PhD in Physics, Materials Science, Chemistry, Engineering or other comparable field. The degree requirement must be met by the beginning of the employment. Good oral and written English skills are required. A problem-solving mindset and good communication and interpersonal skills are essential for the role. The candidate should have extensive background and training in the operation of vacuum instrumentation and ion accelerator technology (such as ion sources and ion beam optics). Hands on experience with ion optics software, such as SIMION, is considered a merit. Experience working with nanomaterials and surface characterisation methods including Raman spectroscopy and transmission electron microscopy are considered an advantage but are not essential. A demonstrated ability to work as part of a team and to mentor graduate and undergraduate students is desired.
