Materials Discovery and Interfaces
In order to fill a fixed-term position in full-time (39.83 hours/week = 100%) at the earliest possible date, we are looking for a
Postdoctoral researcher (m,f,x) in Atom Probe Tomography and Transmission Electron Microscopy of High-Entropy Alloys
The Center for Interface-Dominated High Performance Materials (Zentrum für Grenzflächendominierte Höchstleistungswerkstoffe, ZGH) at the Ruhr-Universität Bochum is looking for a postdoctoral researcher (m/f/x) as soon as possible. ZGH develops new materials through comprehensive understanding and design of material interfaces, exploiting new combinations of structural and functional properties. ZGH is equipped with a set of high-end research equipment for the investigation of surfaces and interfaces of materials, such as atom probe tomography (APT) and high-resolution transmission electron microscope (TEM).
For the Collaborative Research Centre (CRC) 1625 (Atomic-scale understanding and design of multifunctional compositionally complex solid solution surfaces, https://www.ruhr-uni-bochum.de/crc1625/index.html.en), we are looking for a postdoctoral researcher for the project B01 (Accelerated atomic-scale exploration of phase evolution in CCSS systems using combinatorial processing platforms). The aim of this project is to investigate the surface composition and the phase stability of compositionally complex solid solution (CCSS) systems by APT and TEM, and to contribute to achieve the goal of the CRC: mastering surface atom arrangements. We are looking for a highly motivated scientist with a strong background in materials science or in a related field with a focus on thermodynamics and kinetics of phase transformations and/or materials characterization. Strong motivation to work independently, effective teamwork, efficient translation of results into scientific publications, and very good communication skills are expected of the future postdoctoral researcher. Please upload your complete and informative application documents (informative letter of motivation, CV with certificates, complete list of publications and your 3 most important own publications) as one pdf document.
Scope: full-time

The Ruhr-Universität Bochum is one of Germany’s leading research universities, addressing the whole range of academic disciplines. A highly dynamic setting enables researchers and students to work across the traditional boundaries of academic subjects and faculties. To create knowledge networks within and beyond the university is Ruhr-Universität Bochum’s declared aim.
The Ruhr-Universität Bochum stands for diversity and equal opportunities. For this reason, we favour a working environment composed of heterogeneous teams, and seek to promote the careers of individuals who are underrepresented in our respective professional areas. The Ruhr-Universität Bochum expressly requests job applications from women. In areas in which they are underrepresented they will be given preference in the case of equivalent qualifications with male candidates. Applications from individuals with disabilities are most welcome.
