Postdoc In Two-Dimensional Orbitronics And Memory Device Studies With Angle-Resolved Photoemission Spectroscopy

The Department of Physics and Astronomy, Aarhus University, invites applications for a 2-year postdoc position, starting September 1st 2026, offering applicants an exciting opportunity to join a new research project on orbitronics and metastable states in two-dimensional quantum materials. The project involves fabrication of devices and their integration with the existing angle-resolved photoemission (ARPES) infrastructure at the ASTRID2 light source to discover quantum geometric effects and their link to new forms of transport phenomena.

You are expected to contribute to the development of new types of 2D material devices that can realize orbital, spin and valley Hall effects that form the basis for prototypical memory devices. You will command and expand a series of novel infrastructures to achieve these goals, including semi-automated fabrication systems in inert environments, clean-room facilities for device production, micro-focused synchrotron light for ARPES characterization at ASTRID2 as well as ultrafast femtosecond laser pulses for optical control of the materials.

• You will take a leading role in defining, designing and manufacturing advanced 2D devices that are compatible with our microARPES experiment at ASTRID2 with the specific aim to uncover orbital-driven phenomena in materials.
• The scientific goals are to combine synchrotron and ultrafast laser sources to visualize, excite and control electronic states with distinct orbital and spin textures in quantum materials.
• You will work with metallic and semiconducting transition metal dichalcogenide, including materials that are sensitive to ambient conditions, which requires development of new techniques to isolate and integrate such materials with devices for photoemission experiments carried out in UHV conditions.
• You are expected to play a leading role in the laboratory and be the main driver for maintenance and upgrade activities in relation to the device fabrication infrastructure as well as their interface to the ARPES and laser systems.
• You are expected to contribute to the training and education of students in relation to project activities, as well as being a team-player in the group in relation to being open and supportive of your colleagues and in group related activities.

Applicants should hold a PhD in Condensed Matter Physics (or related field) and are expected to have experience within the following research areas:

• Electronic structure of two-dimensional materials (f.ex. graphene, hBN and monolayer transition metal dichalcogenide semiconductors)
• Angle-resolved photoemission spectroscopy or similar techniques to probe excitations in solids
• Experience with exfoliation and stacking of 2D materials and their heterostructures, as well as integration with device architectures.

The applicant is required to demonstrate:

• A good track record of designing, maintaining and applying ultrahigh vacuum systems in the context of experimental physics.
• Use of synchrotron beamline facilities to investigate properties of matter

The applicant is expected to be a team-player that is strongly motivated to work with students and external collaborators, as well as being supportive and open towards other group members.
