The Peter-Grünberg-Institute - Functional Nanostructures at Surfaces (PGI-3) at Forschungszentrum Jülich investigates fundamental issues in the quest towards functional nanostructures at surfaces, with a particular emphasis on nanoelectronics. Since our focus is placed on molecular materials, an important aspect of our work covers the structural investigations and spectroscopy of complex molecular adsorbates on metal, semiconductor and insulator surfaces. Based on these interface studies, the growth of thin films and nanostructures is investigated. Here, our work is directed towards hybrid materials, comprising both organic and inorganic components. Charge transport, being the most important function in the context of nanoelectronics, transport experiments on single molecules and nanostructures round off our activities. It is a specific asset of our institute that we combine well-established surface techniques with the development of new experimental methods.

The project is part of the excellence cluster Matter and Light for Quantum Information (ML4Q), which has been granted for 7 years starting in 2019 (https://ml4q.de/). A major goal of the cluster is the realization of scalable Majorana qubits.

In order to probe in-situ prepared Majorana bound states for quantum computation directly after preparation in ultra-high vacuum, a new instrument should be developed, which combines existing expertise in Aachen and Jülich regarding 4-tip STM, low-temperature STM down to 300 mK and time-resolved STM down to ca. 100 ps. The instrument will be based on a commercial cryostat and is housed in an acoustically and electrically shielded room, which is located on air-damping legs, at Forschungszentrum Jülich. An existing 4 K-4-tip-STM can be used to proceed with research during the build-up of the new system.

We are looking to recruit a

Postdoc “Development of a low temperature 4-tip STM”

Your Job:

  • Developing the worldwide first 4-tip STM operating at 20 GHz and below 1 K
  • Planning of the cryostat design in combination with scanning electron microscope column
  • Experimental charge transport studies with an existing instrument and the new instrument on materials and structures important for topological quantum information
  • Close cooperation with the scientific and engineering staff in the Forschungszentrum Jülich and the RWTH
  • Scientific cooperation with other groups in Forschungszentrum Jülich and within the ML4Q cluster of excellence
  • Supervision of Ph.D. students working together the same subjects
  • More information can be also found at http://www.institut2b.physik.rwth-aachen.de/wp-content/uploads/2019/02/Postdoc-Ml4Q.pdf

Your Profile:

  • PhD degree in Physics or Engineering Sciences
  • Background either in 4-tip STM or in low-temperature STM
  • Skills in construction of new scientific instruments
  • Good communication and organisational skills are essential
  • Good written and spoken English skills

Our Offer:

  • Excellent research and computing infrastructures in one of Europe’s largest research facilities
  • Exciting working environment on an attractive research campus with excellent infrastructure, located between the cities of Cologne, Düsseldorf, and Aachen
  • International and interdisciplinary working atmosphere
  • A comprehensive further training programme
  • Flexible working hours and various opportunities to reconcile work and private life
  • Limited until 30.06.2022 with possible longer-term prospects
  • Salary and social benefits in conformity with the provisions of the Collective Agreement for the Civil Service (TVöD)
