Stimulated by major needs and challenges in science and a sustainable society, the ambition of the department of Physics is to foster a creative environment for academic research, learning and outreach.
We provide a competitive advantage by linking our top-level international and interdisciplinary academic performance in the areas of material science, nanotechnology and energy research with world-leading industrial R&D&I projects.
We address a wide array of experimental, computational, methodological and theoretical challenges, from fundamental physics research, through the development of new materials such as graphene to direct industrial projects generating new inventions.
We have a strong learning commitment on all levels from undergraduate to PhD studies where physics meet engineering. We are situated in a stimulating and creative environment with attractive facilities located in central Gothenburg. The department is part of Gothenburg Physics Centre - a collaboration between five departments at Chalmers and Gothenburg University.

An increasing demand for sustainable, energy-efficient, and environmentally-friendly devices necessitates the use of novel and inherently sustainable materials at the smallest scales. Consequently, there has been an active search for innovative and inherently sustainable materials at the nanoscale level in recent years. Among the most promising materials are atomically thin two-dimensional (2D) semiconductors, specifically transition metal dichalcogenides (TMDs) such as MoS2 and WSe2. These materials hold great potential in applications such as solar cells for energy harvesting and tunnel-field effect transistors for energy-efficient computing and data storage. The success of these 2D materials in such applications is deeply connected to their electronic and atomic properties.
The present project aims to explore the heterostructures of 2D materials for all-2D field-effect transistors and solar cells using first-principles modeling. This project will be conducted in close collaboration with experimentalists at the MC2 department at Chalmers and has the potential to revolutionize the development of cutting-edge, sustainable devices.
Information about the division and the department
The Division of Condensed Matter and Materials Theory comprises several dozen enthusiastic scientists working on theoretical aspects of condensed matter physics and materials science. We construct models for and develop an understanding of a large variety of materials and other condensed matter systems, sometimes leading us to new materials, novel technological devices, or structured media with properties beyond those of atomic materials. To this end, we combine analytical and computational techniques, often in close collaboration with local and international experimental groups. The work in the division is characterized by a strong interplay between fundamental and applied research. This allows us to address important societal challenges, e.g., related to sustainable energy or information technology.
Major responsibilities
You will work on modeling the electronic structure of heterostructures of 2D materials with applications in tunnel field-effect transistors and solar cells. You will calculate band structures and band alignments of different combinations of materials, as well as assess the effect of for example defects and temperature on these properties. The calculations will be performed based on density functional theory codes such as VASP and CP2K. There is possibility of using molecular dynamics and machine learning within the project. You will also contribute to the search and optimization of materials and devices in collaboration with experimental groups. As part of the project, you will be expected to report to the experimental collaborators and communicate research results both orally at international conferences and in writing in scientific journals.
Your major responsibility as postdoc is to perform your own research in a research group. The position may also include teaching on undergraduate and master's levels as well as supervising master's and/or PhD students to a certain extent. Another important aspect involves collaboration within academia and with society at large. The position is meritorious for future research duties within academia as well as industry/the public sector.
Qualifications
You should hold a doctoral degree in physics, chemistry or materials science and have a documented experience in computational modeling and electronic structure calculations. You should enjoy working in a collaborative environment including interactions with both theoreticians and experimentalists
To qualify for the position of postdoc, you must hold a doctoral degree awarded no more than three years prior to the application deadline (according to the current agreement with the Swedish Agency for Government Employers). The position requires sound verbal and written communication skills in English. Swedish is not a requirement but Chalmers offers Swedish courses.
Contract terms
This postdoc position is a full-time temporary employment for two years.
