The recruitment is connected to the Wallenberg Initiative Materials Science for Sustainability (WISE), which is funded by the Knut and Alice Wallenberg Foundation and is the largest-ever investment in materials science in Sweden. All early-stage researchers recruited into the WISE program will be part of the WISE Graduate School, an ambitious nationwide program of seminars, courses, research visits, and other activities to promote a strong multi-disciplinary and international network between PhD students, postdocs, researchers, and industry.

The project will be conducted within the research group of Prof. Maths Karlsson at the Department of Chemistry and Chemical Engineering, Chalmers University of Technology, Sweden. The group focuses on characterization of structure and dynamics in "functional" materials, with a view towards their implementation in energy-relevant technologies, such as LEDs, solar cells, batteries and fuel cells. The primary tools to this end involve the use and development of techniques at large-scale neutron and photon sources, vibrational spectroscopy, optical techniques, and computer modelling. Almost all of the work is carried out in collaboration with other leading research groups, in Sweden and in many other countries.
About the project
Lighting stands for 16.5% of the world's electricity consumption. Novel and energy efficient lighting is therefore needed to reduce the impact on the environment originating from this enormous energy consumption. Phosphor-converted LEDs have become mainstream for many lighting applications, but a remaining challenge is the strong reduction of the light emittance upon increasing temperature, known as thermal quenching of luminescence. The overriding goal of this research program will be to develop a fundamental understanding of thermal quenching of luminescence in a promising class of novel phosphor materials, namely halide double perovskites (see e.g., J. Luo et al., Nature 563 (2018) 541). The project is experimental in nature and focuses on physical and optical characterization of halide double perovskites, using a combination of in-house optical techniques, as well as techniques at international large-scale neutron and photon sources around the world, especially the Institut Laue-Langevin (France), ISIS Neutron Source (U.K.), Spallation Neutron Source and NIST Center for Neutron Research (U.S), J-PARC (Japan), Paul-Scherrer Institute (Switzerland), and the Extreme Light Infrastructure Beamlines (Czech Republic).
Major responsibilities
Your major responsibility will be to carry out the PhD project, as described briefly above. You are expected to develop your own scientific concepts and communicate the results of your research in a wide context, e.g., through meetings, seminars, national and international conferences, and in the form of informal reports, and peer-reviewed publications. As a PhD student, you will as well take courses corresponding to 60 ECTS and be involved in teaching on the undergraduate level corresponding to about 10% of your time.
Qualifications
To qualify as a PhD student, you must have a master's level degree corresponding to at least 240 ECTS in a relevant field such as physics, materials science, or chemistry. To be successful, you need to be highly motivated and have high analytical and communication skills. Given the strong international nature of the project, and the collaboration with several research groups and facilities around the world, you also need a flexible approach and enjoy traveling.
Contract terms
Full-time temporary employment. The position is limited to a maximum of four years full time PhD study.
