PhD for Local Sensing of Collective Spin Phases in Semiconducting Moiré Materials University of Basel in Switzerland

The Quantum Opto-Electronics Group (QOEG) at the Department of Physics, University of Basel, led by Prof. Dr. Tomasz Smoleński and in collaboration with Prof. Martino Poggio, invites applications for a PhD position focused on the local sensing of collective spin phases in semiconducting moiré materials (SMMs). This research aims to advance the control of magnetism at the nanoscale, leveraging the unique properties of SMMs—twisted or lattice-mismatched monolayers of van der Waals crystals with flat electronic bands and excellent optical characteristics.

Embedded in gated heterostructures, SMMs host a variety of collective spin phases, serving as artificial quantum materials that provide direct optical access to spin physics and offer tunability comparable to cold-atom simulators. The project will integrate optical spectroscopy with SQUID-on-tip (SOT) magnetometry, combining the dynamical control of optical experiments with the spatial resolution of SOT. This hybrid approach enables simultaneous application of both techniques on a single device, opening new avenues for fundamental research and nanotechnology applications.

As a PhD student, you will participate in all aspects of research, including engineering and fabricating electrically-tunable devices, designing and assembling experimental setups, and performing magneto-optical measurements. The University of Basel offers a vibrant, international research environment with cutting-edge infrastructure, fostering openness, diversity, team spirit, and scientific curiosity.

Applicants should hold or expect to soon obtain an MSc degree in Physics, Electrical/Optical Engineering, or a closely related discipline. A strong background in condensed matter physics and optics, excellent academic record, experience with data analysis and software tools for automated measurement, and proficiency in English are required. Desirable qualifications include research publications, experience in scanning probe experiments (STM, NV magnetometry, SQUID-on-tip), and clean-room processing or handling van der Waals materials.

To apply, submit your application via the University of Basel's online recruiting tool, including your CV, publication list, conference presentations, and contact details of at least two referees. Applications will be reviewed until the position is filled. The deadline for initial review is July 2, 2026.
