Information about the Department of Chemistry and Chemical Engineering

Chemistry and Chemical Engineering is the largest department at Chalmers with research ranging from the most fundamental level to a level close to application in industry and society. The research activities reach from DNA-research, biomaterials and polymers to high temperature corrosion, catalysis and recycling. The Department is also heavily committed to teaching at the undergraduate, graduate, as well as postgraduate level in these areas.

Health, natural resources, sustainable energy and materials are some of our lead words and our vision is “Through curiosity and knowledge towards a sustainable world”.

We have approximately 300 employees, divided into four research and one administrative division. We are situated at campus Johanneberg in the middle of Gothenburg.

Information about the Research Group

The Müller Research Group focuses on the physical chemistry and materials science of organic semiconductors, polymer blends and composites, and develops new plastic materials for energy technologies ranging from organic solar cells and thermoelectrics to power cables. All research is conducted in co-operation with other universities/institutes and/or industry. Presently, the Müller Research Group consists of 1 Associate Professor, 5 Postdocs, 8 PhD students and several Master students.

Information about the Research Project

We are looking for a highly motivated student to join our research team at Chalmers. The successful candidate will have a Master degree in Chemistry, Physics, Physcial Chemistry, Materials Science, or equivalent. Previous experience within the field of organic electronics is preferred. A strong foundation in Physical Chemistry is expected.

The PhD project is part of the Knut and Alice Wallenberg-funded research programme ”Mastering Morphology for Solution-borne Electronics”, in which research groups from Chalmers, Karlstad University, Linköping University and Lund University collaborate. The main goal of the project is to predict and monitor the structures that are formed in thin organic semiconductor films during drying of multi-component solutions, in order to optimise their properties for use as functional materials in electronic devices. To reach this goal we will develop and use methods to follow the dynamics of structure formation in-situ, to determine local film composition and structure, and to understand the underlying thermodynamic mechanisms.

The goal of your project will be to study glass formation in mixtures of organic semiconductors; a concept which is of high interest for electronic devices ranging from organic solar cells to field-effect transistors. You will use a number of experiemental techniques, such as thermal analysis, rheology, grazing-angle X-ray difraction, and various spectroscopic tools to study the solidification kinetics of organic semiconductor mixtures. Experimental work will be correlated with the underlying physical chemistry, including theoretical work, in order to build up a complete picture with regard to glass formation of organic semiconductors. Finally, you will test the developed materials concepts in devices such as organic solar cells. For specific examples of the type of research questions that you will tackle we refer to the following publications: Adv. Mater. 2015, 27, 7325; Chem. Mater. 2015, 27, 2740.

Major responsibilities

The majority of your working time is devoted to your own research studies. As a PhD student you are expected to develop your own ideas and communicate scientific results in English, both orally as well as in writing. In addition, the position will normally include 5% departmental work, mostly teaching duties. Undergraduates are normally taught in Swedish, although the graduate level teaching is in English. Applicants whose native language is not Swedish are encourgaed to learn Swedish during the first two years of their studies.

Position summary

The employment is limited to a maximum of four years full-time research studies. 


The successful candidate will have a Master degree in Chemistry, Physics, Physcial Chemistry, Materials Science, or equivalent. Previous experience within the field of organic electronics is preferred. A strong foundation in Physical Chemistry is expected.

Experience with materials characterisation tools such as SEC-GPC, NMR, FTIR, thermal analysis (DSC, TGA), X-ray diffraction (WAXS, SAXS) optical and electron microscopy and/or rheology 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.

Chalmers continuously strives to be an attractive employer. Equality and diversity are substantial foundations in all activities at Chalmers.
