Offer Description

Our Profile

The Institute of Physical Chemistry at RWTH Aachen University consists of several research groups covering a very broad range of topics. The focus is on investigating the physicochemical properties of various materials: from inorganic solids and molecular materials to macromolecules and nanoparticles in solution.

The research group of Prof. Dr. Roger A. De Souza uses experimental and computational methods to investigate the properties — in particular ion transport — of materials used in energy and information technology, such as solid oxide fuel cells, ReRAM technologies, solar cells, etc. The working environment is collegial and supportive. For example, weekly team meetings provide an opportunity to discuss current research results and jointly develop solutions to scientific challenges.

Your duties and responsibilities

Doctoral position on the topic:
“Ion transport studies to elucidate the defect chemistry of Zn-conducting oxides with spinel structure”

• Combining theoretical and experimental methods to investigate and improve the ionic and electronic transport properties of spinel materials for energy storage
• Investigating cation and anion doping in ZnMn₂O₄- and ZnFe₂O₄-based materials and their influence on transport and material properties
• Characterizing zinc-ion diffusion as well as chemical and structural stability during the insertion and de-insertion of Zn²⁺
• Performing and evaluating various experimental and computational studies to elucidate the underlying transport and defect mechanisms
• Publishing results in peer-reviewed journals and presenting them at international conferences
