Postdoc in low-temperature nanoscale angle-resolved photoemission (nanoARPE

at  Aarhus Universitet

Are you interested in experimental condensed matter physics using synchrotron radiation and can you contribute to the newly funded ERC Consolidator Grant project EXCITE? Then the Department of Physics and Astronomy, Aarhus University, invites you to apply for a fulltime 2-year postdoc position, starting 1 February 2025, in order to help commission a cryogenic cooling system on the nanoARPES beamline of ASTRID2 and use the capability to study novel correlated electronic phases in quantum materials.

JOB DESCRIPTION

You are expected to contribute to the commissioning of a new cryo-cooling system on the existing SGM4 nanoscale angle-resolved photoemission spectroscopy (nanoARPES) beamline of the synchrotron radiation source ASTRID2 and use it to study correlated phases in 2D materials, devices, twisted superstructures, bulk quantum materials and heterostructures.

• You will take an active role in installation, testing and development activities surrounding the cryo system and integrating it with the SGM4 infrastructure.
• The scientific aim is to measure hidden phases of correlated electrons as a function of temperature, doping and optical excitation parameters (using a femtosecond laser source in combination with our synchrotron ASTRID2).
• You will probe transition metal dichalcogenide charge density wave compounds, high temperature superconductors and Mott insulators in combination with 2D materials such as graphene. You will integrate these compounds in devices that are compatible with photoemission experiments.
• You are expected to play a key role in keeping the nanoARPES system with attached laser and sample preparation systems running by leading maintenance and upgrade activities, as well as participate in activities and projects surrounding our ASTRID2 Institute of Storage Ring Facilities (ISA).
• It is required that you are willing to participate in external beamtimes, adding complementary information on the probed samples, at international synchrotrons and ultrafast laser facilities in Europe and the USA by contributing leadership at the experiments at the facilities.
• These main tasks are performed as part of the objectives of an ERC Consolidator project called EXCITE.

WHO WE ARE

You will take part in a research team that is strongly devoted to uncovering electronic properties of new materials and develop state-of-the-art synchrotron- and laser-based techniques. Our research is based around the synchrotron source ASTRID2 in Aarhus where we operate a beamline for angle-resolved photoemission experiments, in addition to hosting facilities for isolating and transferring 2D materials. We have strong collaborative ties with some of the most advanced international facilities for conducting photoemission experiments on nanoscale and two-dimensional materials, providing ample opportunity for networking. The research program is organized under an ERC Consolidator Grant project (EXCITE).
