Postdoctoral Research Assistant in First Principles Computational Condensed Matter Physics

Contract type: Fixed-term (18 months)

Applications are invited for a Postdoctoral Research Assistant in Computational Condensed Matter Physics.

The post is available initially for a fixed-term duration of 18 months.

This project will focus on understanding the excited state properties of complex heterogeneous semiconductors which are highly attractive for applications to novel optoelectronic devices, in particular photovoltaic devices. The project will utilize and further develop upon state-of-the-art computational modelling techniques to predict excited state properties of complex materials, including but not limited to their quasiparticle band structure and exciton binding energies, as well as their vibrational and transport properties.

This role will utilize several state-of-the-art computational modelling techniques, in particular density functional theory (DFT) and many-body perturbation theory (MBPT) based methods, in order to predict photophysical properties of novel semiconductors. The theoretical and computational predictions emerging from this work will be correlated on a regular basis with parallel activities on materials synthesis and spectroscopic characterization. The goal of this project is to understand and predict excited state properties of new complex semiconductors and develop new computational frameworks and workflows to achieve improved predictive power and efficient analysis. The post-holder will have the opportunity to teach.

Applicants should possess or be close to obtaining a PhD in physics, materials science, or physical chemistry. They should be highly experienced in advanced first principles computational modeling techniques, and in particular in density functional theory and many-body perturbation theory-based methods such as the GW+BSE framework. Applicants should have extensive experience in applying these methods to complex heterogeneous semiconductors. Knowledge of semiconductor physics and a track record of working with next-generation novel materials for light-harvesting is essential.

Applicants should be highly motivated and have excellent skills in working collaboratively, as part of a team. A good track record of high-quality publications is essential. Having the ability to direct your own research and interpret your results independently is a must. The University of Oxford and the Department of Physics offer an inclusive and diverse environment and workplace. We strongly encourage applications from all backgrounds and genders to apply.
