"Doctoral Researcher (f/m/d) within DFG Research Training Group GRK 2948"

The DFG-funded Research Training Group “Mixed Ionic-Electronic Transport: From Fundamentals to Applications” (www.grk2948.uni-heidelberg.de) is an interdisciplinary structured doctoral programme at Heidelberg University and the University of Stuttgart. We explore how ions and electrons interact with each other in organic, hybrid and nanoscale materials with the aim to create new functionalities for sensors, soft actuators and bioelectronics. The fundamental nature of ion-electron interactions in relation to electronic, optical and mechanical properties are investigated with a wide range of modern techniques such as in-situ and time-resolved spectroscopies/microscopies as well as rheological measurements on different length scales. Experiments are accompanied by modelling from the atomistic level to the macroscale.

Pursuing a doctoral degree within this Research Training Group (RTG) offers you a combination of fundamental and applied research topics, close collaboration across disciplines in a collaborative and diverse environment, exchanges with international partners and a tailored qualification programme. It will enable you to pursue a successful career within the fast-expanding field of mixed ionic-electronic conductors that are applied in functional opto-electronic, electrochemical, and bioelectronic devices.

Exciting research projects from theory to synthesis and device engineering are either located at Heidelberg University or the University of Stuttgart.
