PhD student position in Materials Chemistry for Stable Organic Electronics

We are looking for a highly motivated PhD student to join the project “Stable Doping of Organic Semiconductors”, supported by the Knut and Alice Wallenberg Foundation.

The project brings together 5 research groups from Chalmers University of Technology and Linköping University, led by Christian Müller, Anna Martinelli, Eva Olsson, Mats Fahlman and Simone Fabiano. The mission of the project is the realization of doped organic semiconductors that display truly stable electronic behaviour. You will be part of a team of five PhD students, as well as several Postdocs, who will together develop and study new materials concepts that facilitate stable doping. You will have the opportunity to visit and collaborate with different research labs both in Sweden and abroad.

Project description

Doping is essential for the optimization of the electronic performance of organic semiconductors, and as such essential for a wide range of emerging technologies from sustainable energy harvesting via organic photovoltaics and thermoelectrics to wearable electronics and bioelectronics. The doping process involves a chemical or electrochemical reaction that allows to tune the electrical and electronic properties of an organic semiconductor. The resulting doped state, however, is prone to evolve with time, which limits the lifetime of electronic devices.The project will leverage concepts from the field of molecular glasses to realize stable organic semiconductors and devices. Your specific project will entail a detailed study of the phase behaviour and glass formation of dopant/semiconductor pairs, using a suite of characterization methods from thermal and mechanical analysis to optical spectroscopy and various scattering techniques.It can be anticipated that the project will have considerable impact on the field of organic electronics by enabling the more widespread usage of some of the most promising materials, which will accelerate further development of many emerging technologies.

Information about the division and the department

The Müller Research Group at the Department of Chemistry and Chemical Engineering at Chalmers Docuses on the physical chemistry and materials science of organic semiconductors, polymer blends and composites, and develops new plastic materials for use in the fields of wearable electronics and energy technology. All research is conducted in co-operation with other universities/institutes and/or industry. Presently, the group consists of 1 Professor, 1 permanent researcher, 3 Postdocs and 8 PhD students.

Major responsibilities

The majority of your working time is devoted to your own research, in collaboration with postdocs and students at Chalmers and Linköping University. As a PhD student you are expected to develop your own ideas and communicate scientific results orally as well as in writing. In addition, 10 percent of your time will be dedicated to departmental duties, especially teaching on the undergraduate level.


The successful candidate must have a Master’s degree in Chemistry, Materials Science or equivalent (or be in the process of completing a Master’s degree). Experience with organic electronics is required; experience with polymer science is a merit. Due to the interdisciplinary nature of the work, the candidate is expected to have excellent collaboration skills. A very good capability of communicating scientific results in English, both orally and in writing is required.The position requires sound verbal and written communication skills in English. If Swedish is not your native language, Chalmers offers Swedish courses.

Contract terms

Full-time temporary employment. The position is limited to a maximum of four (4) years of fulltime research studies.
