Kurzbeschreibung

Research Associate "Characterisation of high-entropy nanostructures utilizing modern X-ray methods" § 28 Subsection 1 HmbHG Institution: Cluster of Excellence „CUI: Advanced Imaging of Matter“ (photon and nanosciences) Salary level: EGR. 13 TV-L Start date: 01.01.2027, fixed for a period of three years. (This is a fixed-term contract in accordance with Section 2 of the academic fixed-term labor contract act [Wissenschaftszeitvertragsgesetz, WissZeitVG]). Application deadline: 2026-11-19 Scope of work: part-time Weekly hours: 75 % of standard work hours per week Your responsibilities Research associates will be expected primarily to teach and conduct research. The research associate will also have the opportunity to pursue further academic qualifications, particularly a doctoral dissertation. At least one-third of set working hours will be made available for the research associate’s own academic work. Teaching duties currently comprise 3.0 teaching hours per week. We invite a highly motivated candidate to develop innovative synthetic methods for producing high-quality high-entropy nanostructures—including particles and thin films—and to uncover their emergent nanoscale properties. This position sits at the interface of materials synthesis, advanced nanoscale characterization, and state-of-the-art experiments at large-scale X-ray facilities. A core part of the project will be to design experiments and carry them out at synchrotrons and XFELs, together with other cutting-edge characterization approaches. The goal is to study structure and dynamics in situ/operando and to establish how nanoscale structure governs material performance—knowledge that directly enables materials design for energy conversion and environmental technologies. The successful candidate will work with a high degree of independence while collaborating closely with group members, members of Cluster of Excellence ‚CUI: Advanced Imaging of Matter and external facility teams. Key responsibilities: • synthesize, fabricate, and optimize high-entropy nanostructures (particles and films) with controlled composition and microstructure • characterize structure and properties using established laboratory techniques and advanced analytical tools • plan, prepare, and execute synchrotron/X-ray experiments, including sample preparation, experiment support, and iterative optimization • participate in time-resolved in-situ/operando measurements, including data analysis and interpretation in collaboration with experts • contribute to scientific reporting through oral presentations and publications What you can expect: • hands-on experience with leading experimental platforms (synchrotrons/XFELs) and time-resolved nanoscale characterization • exposure to experiment-driven materials development, from synthesis → characterization → mechanism • opportunities to help shape the direction of a research program focused on tunable, high-performance high-entropy materials Your profile A university degree in a relevant field. Required qualifications: • applicants should hold a Master’s degree in nanoscience, physics, materials science/engineering, or a closely related field • a proven solid foundation in solid-state physics or materials physics • prior experience with synthesis and/or fabrication of nanostructures and structural/functional characterization, e.g., AFM, SEM, TEM, PXRD/RXRD, and/or XAS/XES • demonstrated experience with synchrotron- and/or XFEL-based experiments, including sample preparation and experiment support • strong skills in data analysis and interpretation, ideally including methods such as Rietveld refinement and X-ray spectroscopy workflows and/or codes (e.g., ORCA, FDMNES) Assets (highly beneficial) • good programming skills and experience handling large datasets, preferably with Python • experience with complementary laboratory techniques such as UV–Vis, FTIR, and TGA • experience with colloidal synthesis and/or high-vacuum equipment and cleanroom workflows Communication • excellent communication skills are essential. Fluency in English is required, as the position involves collaboration in an international research environment • knowledge of German is an asset We offer Reliable remuneration based on wage agreements Continuing education opportunities University pensions Attractive location Flexible working hours Work-life balance opportunities Health management, EGYM Wellpass Educational leave 30 days of vacation per annum Universität Hamburg—University of Excellence is one of the strongest research educational institutions in Germany.
