Positions for PhD students:

We are seeking applications for a

Research Assistant (Praedoc)

(fare based on german 3/4 E13 TV-L FU) in experimental solid-state physics, starting from April 1st, 2021 and limited to three years. The PhD-student position is assigned to the workgroup of Prof. W. Kuch, which has experience investigating ultrathin magnetic films, surfaces, adsorbed magnetic molecules, and nanostructures that may become relevant in a future spin-based electronics. One focus of research is on the reversible manipulation of the magnetic properties of adsorbed molecules. Experiments are carried out both by laboratory-based techniques as well as by using synchrotron radiation.

The project consists of research in the field of x-ray spectroscopy of adsorbed spin-crossover molecules with the goal to tailor the cooperativity in the thermal and light-induced spin transitions of these systems. Due to the possibility to switch their molecular magnetic moment on and off by external means, spin-crossover molecules are highly interesting candidates for programmable building blocks in molecule-based spin electronics if they can be immobilized and contacted, which implies that they are supported by a solid surface. In order to improve the switching on solid surfaces, the cooperativity, which often accompanies spin transitions of SCO molecules in solids and can lead to hysteresis, has to be re-established on surfaces. In this research project, funded by the German Science Foundation (DFG), a range of spin-crossover structures from mononuclear spin-crossover molecules to dimers, trimers, and infinite chains are deposited on solid surfaces by different techniques and characterized by x-ray absorption and x-ray photoelectron spectroscopy in order to gain comprehensive knowledge about the factors establishing cooperative spin switching of molecules adsorbed on solid surfaces. Experiments will be carried out in the university laboratory in Berlin-Dahlem and at the synchrotron radiation source BESSY II in Berlin-Adlershof. The third-party funded research project provides an opportunity to do a doctorate.

A master's degree in physics or physical chemistry is required. We are seeking a motivated candidate with team spirit and ability for independent work. A master thesis in experimental physics, experience in surface science, with ultrahigh vacuum technology, spectroscopy using synchrotron radiation, or adsorbed molecules are desired.

The Freie Universität is an equal opportunity employer. Women are strongly encouraged to apply. Applicants with a disability are given preference in case of equal qualification.

Postdoc positions:

Currently there are no open positions available. However, funding for postdocs from abroad may be obtained from one of several funding agencies, for instance, from the Alexander von Humboldt Foundation, or from specific funding programs for your country of residence/citizenship (see, for example, the website of KoWi, the European liaison office of the German research organisations, or search the country-specific DAAD scholarship database).
