Faculty of Science
The Faculty of Science (FNWI), part of Radboud University, engages in groundbreaking research and excellent education. In doing so, we push the boundaries of scientific knowledge and pass that knowledge on to the next generation.

We seek solutions to major societal challenges, such as cybercrime and climate change and work on major scientific challenges, such as those in the quantum world. At the same time, we prepare our students for careers both within and outside the scientific field.

Currently, more than 1,300 colleagues contribute to research and education, some as researchers and lecturers, others as technical and administrative support officers. The faculty has a strong international character with staff from more than 70 countries. Together, we work in an informal, accessible and welcoming environment, with attention and space for personal and professional development for all.

1. Introduction

The goal of this PhD project is to develop, build and operate a vacuum compatible exfoliation center for the creation of heterostructures constructed from reactive 2D materials.

2. Job description

Recently, two-dimensional (2D) materials, e.g. graphene, have gained much attention in research for their special physical properties compared to their three-dimensional counterparts. Halides or transition metal dichalcogenides in particular, but also many other material compounds, show great potential for future device applications because of their special superconducting, magnetic or transport properties. However, typically these materials are very reactive and deteriorate quickly under ambient conditions or even in the dry atmosphere of a glove box.

Your goal will be to establish a new synthesis method and subsequently investigate these materials using local probes at ultra-low temperatures, including scanning probe microscopy and magneto-transport. Using these newly developed material systems, you will investigate physical phenomena such as superconductivity, charge transport, and unconventional memory/computing. Your teaching load may be up to 10% of your working time. 

Our Scanning Probe Microscopy (SPM) group has long-standing expertise in developing very specialised and world-class scientific instruments [1]. Furthermore, we have successfully explored the surface properties of bulk black phosphorus [2] and demonstrated its potential as a platform for orbital memory [3] and even brain-inspired computing [4]. The next natural step is to investigate materials mentioned above in their 2D limit [5].

3. Profile

  • You obtained a Master’s degree in physics with a Master’s thesis on an experimental research topic.
  • You have good English communication skills (verbal and written).
  • You are keen to further develop your scientific communication skills through presentations and publications.
  • You have a strong interest in condensed matter physics.

4. We are

The SPM department has many international scientists and students. We host world-class SPM instruments and utilise SPM techniques beyond the state of the art to study numerous problems in fundamental physics and chemistry. Our expertise focuses on the development and use of high-precision magnetic and electronic imaging techniques involving single atoms, molecules and surfaces in cryogenic ultrahigh vacuum environments and magnetic fields, often related to single-atom manipulation.

You will join the Scanning Probe Microscopy (SPM) department and collaborate with the High Field Magnet Laboratory (HFML) at the Institute for Molecules and Materials (IMM), which is one of the major research institutes of the Faculty of Science at Radboud University. IMM is a research institute in chemistry and physics, which fosters interdisciplinary research. Its mission is to design and create functional molecules and materials to fundamentally understand their behaviour. The institute comprises 19 research groups in areas ranging from condensed matter science to organic chemistry and biochemistry. IMM focuses on fundamental research with an open eye for societal applications and educates the next generation of leaders in science and innovation. IMM distinguishes itself from similar institutes by close collaborations and rich interactions between chemists and physicists and/or experimentalists and theorists, and an excellent infrastructure including our Scanning Probe Laboratories, Laser Labs, Magnetic Resonance Research Centre, High Field Magnet Laboratory and Free Electron Laser Laboratory (HFML-FELIX).

5. We offer

  • We will give you a temporary employment contract (1.0 FTE) of 1,5 years, after which your performance will be evaluated. If the evaluation is positive, your contract will be extended by 2.5 years (4-year contract).
  • You will receive a starting salary of €2,770 gross per month based on a 38-hour working week, which will increase to €3,539 in the fourth year (salary scale P).
  • You will receive an 8% holiday allowance and an 8,3% end-of-year bonus.
  • You will be able to use our Dual Career and Family Support Service. The Dual Career Programme assists your partner via support, tools, and resources to improve their chances of independently finding employment in the Netherlands. Our Family Support Service helps you and your partner feel welcome and at home by providing customised assistance in navigating local facilities, schools, and amenities. Also take a look at our support for international staff page to discover all our services for international employees.
  • You will receive extra days off. With full-time employment, you can choose between 30 or 41 days of annual leave instead of the statutory 20.
