Postdoctoral scholarship: Tuning physical and chemical properties of transition metal clusters and hybrid carbon-metal clusters by composition and size KU Leuven in Belgium

This postdoctoral scholarship at KU Leuven's Quantum Solid-state Physics (QSP) research unit offers an exciting opportunity to join a dynamic team investigating the physical and chemical properties of transition metal clusters and hybrid carbon-metal clusters. The QSP unit specializes in experimental research on quantum phenomena in solid-state systems, focusing on the tunability of functional electronic properties such as magnetism, superconductivity, and semiconducting behavior in systems ranging from single-atom defects to nanoscale clusters and heterostructures. The successful candidate will work closely with Professors Peter Lievens and Ewald Janssens, contributing to ongoing projects that explore magnetism, optical properties, and chemical reactivity of hybrid clusters.

Key research topics include the interaction of hydrogen with gas-phase carbon-metal clusters and the use of fullerene-transition metal hybrids as catalysts for carbon dioxide reduction. Another major focus is the systematic study of cluster magnetism, particularly how doping Rh, Ho, and Tm clusters with Co and Fe atoms affects their magnetic properties. The postdoc will coordinate daily activities in the gas-phase cluster laboratories, support Master's and PhD students, and develop independent research. Experimental techniques include molecular beam studies using mass spectrometry, in-beam reactivity analysis, infrared and visible light spectroscopy with OPO/OPA tunable lasers, and Stern-Gerlach magnetic deflection experiments.

Most work will be conducted in KU Leuven's molecular beam setups, with additional far-infrared spectroscopy experiments at the FELIX free electron laser facility in The Netherlands. The position is fully funded for two years, offering a competitive bursary and access to university infrastructure. Applicants should have a PhD in physics, chemistry, or a related field, with essential experience in high-vacuum technology and molecular beam setups.

Skills in laser spectroscopy, cluster sources, ion guiding and trapping, mass spectrometry, and quantum chemical calculations are highly valued. The role requires strong teamwork, communication skills in English, and a passion for research. KU Leuven provides an inclusive and supportive environment, and the position is based in Leuven, a vibrant city near Brussels. The start date is as soon as possible, and the application deadline is November 14, 2025.
