Postdoc Advanced MBE of scalable III-V and hybrid metal/semiconductor nanostructures - Research position

Department/faculty: QuTech
Level: Doctorate
Working hours: 38.0 hours weekly
Contract: 1 year initially with prospect of extension
Salary: 2588 - 4084 euros monthly (full-time basis)


QuTech is a growing research institute, in the area of quantum computing. Established in 2013, QuTech is a public-private collaboration between Delft University of Technology (TU Delft) and the Netherlands Organisation for Applied Scientific Research (TNO). In 2014 the institute acquired the status of a national icon. Within QuTech a path is being laid from pure academic research to a combination of scientific research and professional technology development. QuTech's mission is the development of a quantum computer and quantum internet.

Within QuTech, a total of about 180 FTE scientists from TNO and the Faculties of Applied Sciences and Electrical Engineering, Mathematics and Computer Science work in an international, inspiring, and innovative setting with much room for ambition, entrepreneurship and innovation. QuTech is organised into so-called Roadmaps: Fault-Tolerant Quantum Computing, Topological Quantum Computing, Quantum Internet and Computing, Shared Development, and the QuTech Academy.

The roadmap ”Topological Quantum Computing” is one of the leading groups in the field of topological condensed matter physics. Within this roadmap a group, led by Prof. Leo Kouwenhoven, of roughly 40 scientists, engineers and students, uses various semiconductor-superconductor hybrid systems to study the physics of Majorana zero modes. The aim of this research is to explore and develop the next generation of quantum hardware, based on topologically protected quantum bits (qubits). Within the QuTech/Microsoft partnership, the Topological Quantum Computing roadmap operates in close collaboration with the Microsoft Research Station Q in Delft.

Job description

Our research is focused on the development of new hybrid semiconductor-superconductor platforms to enable the application of Majorana bound states for topological quantum computing.

Material science and fabrication are the foundation and the enablers of qubit devices. We deal with complex stacks of different materials combined at the nanoscale and require state-of-the art metrology and in-depth morphological, structural and compositional analysis. Fabrication of qubit devices is a challenging, multi-step process pushing the boundaries of nanotechnology and nano-patterning techniques. You can play a key role in the development of our ground-breaking approach to quantum computing by helping to realize quantum devices with quality and control well beyond the current state of the art.

The aim is to develop applied research projects, in the context of the TU Delft/Microsoft partnership, to further the state-of-art Molecular Beam epitaxy (MBE) on a cluster tool focused on nanoelectronics devices and quantum transport physics; to publish in high-quality journals, pursue intellectual property, and foster collaborative work while inspiring others to do the same. The post does not incorporate teaching duties.

Your activities will include:


  • To conduct research & development in the area of III-V MBE for high mobility and large spin-orbit coupling materials and devices such as III- As, III-Sb;

  • To participate in the operation and maintenance of a research-grade MBE cluster facility and in upgrades and modifications to serve your research goals;

  • To generate and pursue independent research in the field of compound semiconductors, and support the initiation of new ideas;

  • To foster academic and industrial collaborative networks and to supervise and guide (under)-graduate students in MBE and related areas.




Our ideal candidate for this position is an experienced material scientist in the field of compound semiconductors with strong materials characterization skills, has an applied physics & devices interest, and has an affinity for industrial R&D.

  • A PhD in Materials Science, Physics or Engineering with at least one year of relevant postdoctoral or industrial experience in compound semiconductor MBE – specifically III-Vs.

  • Well-established expertise and a significant portfolio of research achievement associated with advanced materials and nanostructure growth of III-As and III-Sb using MBE.

  • Proven expertise of MBE operation, maintenance and hardware upgrades.

  • Demonstrated expertise in materials characterization using techniques such as atomic force microscopy (AFM), Scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and photoluminescence (PL) microscopy, Cathodoluminescence (CL); optical characterization techniques; electrical characterization (Hall, Van der Pauw, Field-effect mobility).

  • An excellent record of high-quality publications in major international journals or relevant patents.

  • Proven ability to participate in a research team and to develop networks and interdisciplinary links with researchers at other institutes to enhance the overall strength of research.

  • Excellent written and oral communication skills in English.

Preference will be given to candidates with experience in device physics, device fabrication, and electrical characterization expertise.
