High temperature dielectric ceramics from next generation relaxor ferroelectrics

Project description

With the support of a multidisciplinary research team and UK and US capacitor manufacturing industries you will design, fabricate and characterise a new type of dielectric ceramic for applications in power electronics related to the renewables sector and for applications in aerospace and automotive industries. The key to producing new, device-quality high temperature ceramic dielectrics is to design materials based on an understanding of how local crystal structure and nano-chemistry control the stability of relative permittivity in relaxor ferroelectrics over wide temperature ranges. This will permit materials with improved performance at temperatures above 200°C to be demonstrated. Your PhD research will benefit from interactions with a multidisciplinary research team of postdoctoral researchers engaged in analysing crystal structure-property relationships in related materials, funded by EPSRC: ‘Analysis of Polar Structure in High Temperature Relaxor Dielectrics: a Framework for Materials Discovery’.

You will gain experience of: electroceramic fabrication techniques; scanning and transmission electron microscopy; X-ray diffraction and EXAFS; electrical characterisation methods.

Entry requirements

Applications are invited from candidates with or expecting a minimum of a UK upper second class honours degree (2:1), and/or a Master's degree in a relevant engineering or science degree, such as (but not limited to) materials science, chemistry or physics.

If English is not the applicant’s first language, they must provide evidence that you meet the University’s minimum English Language requirements: : http://www.leeds.ac.uk/info/123100/admissions/143/entry_requirements.

How to apply

Formal applications for research degree study should be made online through the university's website. Please state clearly in the research information section that the PhD you wish to be considered for is the 'High temperature dielectric ceramics from  next generation relaxor ferroelectrics’ as well as Dr Steven Milne as your proposed supervisor.

We welcome scholarship applications from all suitably-qualified candidates, but UK black and minority ethnic (BME) researchers are currently under-represented in our Postgraduate Research community, and we would therefore particularly encourage applications from UK BME candidates.  All scholarships will be awarded on the basis of merit.
