Postdoctoral Research Assistant

Applications are invited for a Postdoctoral Research Assistant who will  work on an EPSRC UK and NSF USA collaborative project focusing on the development and demonstration of new thin-film perovskite LED architectures that use controllably engineered 2D/3D ‘superlattice’ perovskite structures as the emissive layer.  The aim of the project is to realise new perovskite LED architectures that deliver a step change in power efficiency and stability at display-relevant conditions. 

The position is available for a fixed-term duration of 12 months with the research focus being on perovskite LED architectures, with significant activity employing vacuum deposition methodologies for thin film growth and device fabrication.

This project will bring together the University of Oxford (led by Prof. Henry Snaith, with the University of Cambridge (led by Prof. Richard Friend, Dr. Sam Stranks and Prof. Neil Greenham), and CU Boulder, USA (led by Prof. Seth Marder).

This position will be based within the Clarendon Laboratory, Oxford.  The PDRA will focus on the development and characterisation of thin-film materials and LED devices stacks, including the growth and optimisation of 2D/3D metal halide perovskite heterojunctions and superlattices. The EPSRC National Thin Film Cluster Tool for Advanced Functional Materials will be extensively used by the PDRA. Experience in characterisation of hybrid perovskite materials and devices in at least one of x-ray crystallography, electron microscopy, time-resolved optical spectroscopy or electrical device characterisation is essential. Previous experience in semiconductor thin-film growth via vapour deposition is highly desirable.

The Oxford University activity will aim to develop novel highly emissive and stable superlattice structures, created via vapour phase deposition, which emit in the red, green and blue channels.

These will be integrated into LED devices and characterised for efficiency and stability.

General development of understanding of LED device physics and factors that influence long term operational stability will be explored. 

Applicants should possess or be close to obtaining a PhD in physics, materials science, chemistry or engineering. 

Highly experienced in vapour deposition of metal halide perovskites would be a significant advantage.

Previous experience in LED devices is advantageous, but translatable skills in photovoltaic or other optoelectronic devices also beneficial. 

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 desirable.  Having the ability to direct your own research and interpret your results independently is a must.

Oxford University, The Department of Physics and The Photovoltaic and Optoelectronic Device Group 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.

Only applications received before midday 6 January 2025 can be considered. You will be required to upload a brief statement of research interests, CV and details of two referees as part of your online application.
