Postdoctoral position in hybrid organic-inorganic perovskites for lighting

Do you want to perform basic research on materials for next-generation energy technologies, using the latest methods at international large-scale photon and neutron sources, and develop further into a skilled researcher with attractive career opportunities? Then you should apply for this exciting postdoc position.

Project description
Hybrid organic-inorganic perovskites (HOIPs) exhibit light absorbing and emitting properties, due to electronic excitations, and have attracted enormous attention in the last decade, mostly due to their easy fabrication and huge promise for use in solar cells and light emitting diodes. However, a low stability towards heat and moisture are a big hindrance for using these materials in practical devices. The search for more robust HOIPs has recently shifted the focus to lower dimensional systems, but the underlying mechanisms of the electronic excitations remain unclear.

The aim of this postdoc project is to provide crucial contributions to this important problem by unlocking new fundamental understanding of the coupling between local structure, dynamics and luminescence. Special emphasis is laid on the investigation of local structural properties, using a combination of steady-state structural probes as well as time-resolved spectroscopy and diffraction. The work will be conducted in collaboration with other research groups, at Chalmers and in other countries. Specifically, the postdoc is expected to collaborate with PhD students already present in the group and that focus on neutron scattering studies of the dynamical nature of HOIPs. As part of the responsibilities, the postdoc may, apart from his/her own research, be as well collaborating with several researchers in neighboring subject areas.

The division and the research group
The postdoc will be part of the group of Prof. Maths Karlsson at the Division of Energy and Materials at the Department of Chemistry and Chemical Engineering. Our research, at the interface between physics and materials science, focuses on investigations of structure and dynamics of functional inorganic materials. The overall aim is to develop a deeper understanding of the coupling between materials' functional properties, such as ionic conductivity and luminescence, and their atomic-scale structure and dynamics. The primary tools to this end involve the use of large-scale photon and neutron sources around the world, as well as optical techniques at Chalmers. Most of the work is done in collaboration with several national as well as international research colleagues.

Contract terms
Full-time temporary employment. The position is limited to a maximum of two years (1+1) with the possibility for extension.

Qualifications
To qualify for the position, you must have completed a PhD in Experimental Materials Science, Physics, or a related discipline, at the time of appointment. In practice, this means you already have a PhD or you will be finishing your PhD studies in the near future. The degree should generally not be older than three years.

We are looking for a person with experience from fundamental research on inorganic phosphors and/or hybrid organic-inorganic perovskites. Experience in standard optical techniques, such as photoluminescence spectroscopy and/or thermoluminescence spectroscopy is a must, while experience on time-resolved (pump and probe) techniques, and/or in the synthesis of novel inorganic or hybrid organic-inorganic phosphors is an asset.

To be successful, you need to be highly motivated, independent, and have high analytical, social, and communicational skills. Highest standards of research ethics are a must. Excellent knowledge of English, written and spoken, is also required. With this set, we offer unique opportunities for top notch basic research pertaining to technologically important materials and career development.
