About this position
Leiden University’s Leiden Institute of Physics (LION), in collaboration with the Leiden Institute of Chemistry, is offering a full-time postdoctoral research position focused on graphene edge sensors for single-molecule detection and biopolymer sequencing. The project combines chemistry and physics approaches to build scalable and tunable device architectures based on electron tunneling between graphene electrode edges.
The successful candidate will join a small, highly collaborative team that includes PhD students and staff, working in a research environment with state-of-the-art preparation and measurement facilities, low-vibration lab space, and strong support from mechanical and electronic workshops. The work includes designing and optimizing graphene edge-to-edge tunneling devices, developing electronic signal detection methods, and integrating microfluidic structures with the tunneling platform. The postdoc will also take the lead in scientific publications and may contribute to patent applications.
Applicants should have a PhD in Condensed Matter Physics, Nanoscience, Nanotechnology, or Electrical Engineering, together with documented expertise in nanofabrication, nanoscience, low-current device electronics, or graphene/2D-materials devices. Experience with tunneling devices, especially in liquid environments, is an asset. The position is best suited to researchers with several scientific publications, strong experimental experience, and at least three first-author papers, plus excellent English communication skills, strong independence, and the ability to work well in a team.
The appointment is for up to two years, initially one year and extendable after positive evaluation. The salary ranges from €3,546 to €5,538 gross per month (scale 10 under the Dutch universities collective agreement), with holiday allowance, end-of-year bonus, training, career development, commuting reimbursement, and potential tax advantages for international hires. The vacancy is located in Leiden, the Netherlands, at the Bio Science Park within Leiden University’s Faculty of Science.
Applications must be submitted online by 2026-09-15. Required documents include a cover letter, CV, a short proposal for a new research line within the project, degree transcripts, a copy of the PhD thesis, and two references. For more information, contact Jan van Ruitenbeek at [email protected].

What's required
Applicants should hold a PhD degree in Condensed Matter Physics, Nanoscience or Nanotechnology, or Electrical Engineering. The candidate should have documented expertise in nanofabrication, nanoscience, low-current device electronics, or 2D materials (graphene) devices, evidenced by several scientific publications. Experience with tunneling devices, particularly in liquid, is an asset. Prior experimental experience and at least three first-author publications are expected. Excellent written and spoken English, strong teamwork, high motivation for fundamental research with an application perspective, and the ability to work independently and manage time and progress are required. Candidates must live and be officially registered in the Netherlands or be willing to relocate at the start; a C1 level of Dutch proficiency is expected for international staff, and a basic teaching qualification (BKO) must be obtained within two years if required.
