Chalmers University of Technology in Gothenburg, Sweden, invites applications for a fully funded doctoral student position focused on modeling polarons in emerging energy materials. This opportunity is based in the Department of Physics, specifically within the division of Condensed Matter and Materials Theory, which is renowned for its interdisciplinary research in materials science, nanotechnology, life science, and energy research. The division collaborates closely with both local and international experimental groups, providing a dynamic and innovative research environment.

The research project centers on understanding how polarons—quasiparticles formed by interactions between charges and the lattice—affect the efficiency of materials used in solar-energy devices. By employing advanced electronic-structure calculations, machine learning, and molecular dynamics, the doctoral student will model these effects and contribute to the development of next-generation semiconductors for high-performance solar cells and solar-to-fuel conversion technologies. The work involves developing theoretical frameworks and computational tools to describe charge-lattice interactions, analyzing their impact on material properties, and identifying design principles for improved solar absorbers.

As a doctoral student, you will take advanced courses within the Graduate School of Physics or Materials Science, develop your own scientific concepts, and communicate your research findings both verbally and in writing. The position also includes teaching or other duties corresponding to 20% of working hours, which may extend the appointment up to five years. You will have opportunities to collaborate with experimental partners and present your results at international conferences and in scientific journals.

The position is fully funded from the start, with a starting salary of 34,550 SEK per month (valid from May 25, 2025). Doctoral students at Chalmers are employees and enjoy comprehensive benefits, including access to Sweden’s generous parental leave, subsidized day care, free schools, and healthcare. Chalmers is committed to gender equality and offers Swedish language courses to help international students settle in.

Eligibility requirements include a Master’s degree (120 credits) or a Master’s degree (60 credits) in physics, chemistry, or materials science, or a 4-year Bachelor’s degree for students educated outside Sweden. Strong written and verbal communication skills in English are essential, along with the ability to work independently and collaboratively. Experience in computational modeling, electronic-structure methods, programming, and machine learning will strengthen your application. Physical presence in Sweden is required throughout the study period, and a valid residence permit must be presented by the start date.

To apply, prepare your application in English and attach all required documents as PDF files. Submit your CV, thesis, and transcripts using the application form provided. Incomplete applications and those sent by email will not be considered. The application deadline is March 31, 2026. For further information, contact Associate Professor Julia Wiktor at [email protected].

This position offers a unique opportunity to contribute to cutting-edge research in energy materials and join a vibrant academic community dedicated to scientific excellence and sustainability.
