Development of a novel methodology for X-ray photoelectron spectroscopy depth profiling of thin films and coatings

X-ray photoelectron spectroscopy (XPS) is the primary technique employed to determine the chemical composition of material surfaces, with an analysis depth of approximately 5 nm. To determine the chemical composition of the material beyond this depth, XPS has been combined with ion beam bombardment for over 50 years. This allows repeated material removal and analysis to build up a depth profile of the chemical composition as a function of depth for thin films, coatings and other engineered surfaces.

This project will develop a completely new methodology and approach to XPS depth profiling. The new approach uses cutting-edge technology and you will be working on-site with research scientists and engineers to develop this new technique at ThermoFisher Scientific in East Grinstead, Sussex.

Initially, the work will involve becoming knowledgeable in the theory and experimental use of XPS for the analysis of different materials. Then, the project will combine both scientific instrument innovation at ThermoFisher Scientific with studying electromagnetic radiation-material interactions using a range of advanced materials characterisation techniques, including electron microscopy, atomic force microscopy and XPS at the University.

The work will involve studying various thin films and coatings for applications such as quantum computing, optoelectronics, tribology and corrosion protection. This exciting project offers the possibility of being at the forefront of both scientific instrument development and the fundamental scientific understanding of electromagnetic radiation interactions with material surfaces.
