Postdoctoral Research Associate

Applications are invited for a Postdoctoral Research Associate with expertise in advanced spectroscopic techniques applied to next-generation semiconductors for light-harvesting applications.

The position is available for a fixed term of 36 months from time of appointment.

This project is associated with a new EPSRC/UKRI-funded project entitled “Mastering charge-lattice interactions in novel semiconductors for renewable energy generation”. This collaborative project will tackle the complex array of exciting fundamental science arising in “soft” inorganic and hybrid semiconductors, seeking to develop new understanding to bridge the gap between existing models for well-established hard and soft semiconductors. The resulting discoveries will provide a blueprint for light-harvesting materials, guiding and accelerating the development of next-generation inorganic and hybrid crystalline semiconductors for the net-zero carbon transition. Materials explored will expand from an initial selection of semiconducting metal halides, chalcohalides and metal chalcogenides. The unusual properties displayed by many of these materials, including structural flexibility, strongly anharmonic lattice potentials, ionic migration, nanoscale assembly, or complex charge-screening processes are still poorly understood despite their critical impact on electronic properties and device performance. The project will provide a paradigm shift in our fundamental understanding of the charge-lattice interactions that govern such effects.

This PDRA role will utilize several state-of-the-art spectroscopic techniques, such as transient photoluminescence, absorption & photoconductivity experiments and structural probes, to reveal new understanding of light harvesting materials with intermediate lattice softness. Through a powerful combination of advanced spectroscopic and structural techniques, this postdoctoral project will establish clear correlations and mechanisms linking core properties critical to efficient light-harvesting with basic material properties at an atomistic, electronic and structural level.

Applicants should possess or be close to obtaining a PhD in physics, materials science, or physical chemistry. They should be highly experienced in advanced optical spectroscopic techniques and modelling, e.g. ultrafast (sub-picosecond) photoluminescence, absorption or photoconductivity techniques. 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.

The post-holder will have the opportunity to teach.
