PhD researcher; m​/f​/x laser- diagnostics of electric fields and atomic and molecular

PhD researcher (m/f/x) for laser-based diagnostics of electric fields and atomic and molecular species in atmospheric pressure plasmas

The chair for Experimental Physics V - Spectroscopy of Atoms and Molecules by Laser Methods at the Faculty of Physics and Astronomy, Ruhr University Bochum, investigates physicochemical processes in low and atmospheric pressure plasmas. The research is focused on the development and application of advanced laser-based diagnostics from UV to terahertz (THz) to characterize plasmas and their interaction with surfaces, and on highly sensitive laser-based diagnostics using novel lasers in the mid- and far-infrared, including cavity-enhanced spectroscopy, frequency comb spectroscopy, and THz absorption spectroscopy.

The research covers the entire spectrum from basic research to applied research and research with industrial partners and includes strong collaborations on plasma modelling. Candidates joining our team will contribute to innovative research at the forefront of plasma physics and chemistry as well as laser spectroscopy.

We are looking for a highly motivated doctoral candidate for the project “Highly sensitive measurements of electric fields with electric field induced second harmonic generation (E-FISH), and key atomic and molecular species with THz absorption spectroscopy and cavity-enhanced spectroscopy techniques” funded by the German Research Foundation (DFG) in the framework of the Collaborative Research Centre (CRC) 1316 “Transient Atmospheric Plasmas – from Plasmas to Liquids to Solids” focusing on plasma catalysis ().

The ideal candidate (m/f/x) will work with us on the development and application of laser-based diagnostics to various types of plasma sources and applications within the CRC to unravel the plasma physics and chemistry on topics as diverse as plasma electrolysis, conversion of volatile organic compounds, and biocatalysis.

• Scope: part‑time
• Duration: fixed‑term, 3 years
• Start: at the earliest possible date
