Job Details

Postdoctoral Researcher in Ultrawide Bandgap Semiconductor Power Devices (AlGaN, Ga2O3)

Applications are invited for the role of Postdoctoral Researcher in the Centre for Device Thermography and Reliability (CDTR), to contribute to the advancement of ultra-wide bandgap semiconductor power devices. The CDTR is leading the £5M EPSRC Programme Grant ULTRAlGaN to develop the next generation of 2-10kV power devices based on AlGaN (Ga- and Al-polar). ULTRAlGaN’s partners include the University of Cambridge, Manchester and Nottingham. A particular focus of this position is to contribute to the processing of AlGaN power devices and the implementation of new AlGaN device concepts aimed at by ULTRAlGaN. You will also have the opportunity to access the extensive device testing suite available in Bristol, from advanced electrical, thermal to electric field analysis of devices, and simulation tools (ATLAS, ANSYS), and collaborate within our 20-member team as well as with the ULTRAlGaN academic and industrial partners. Bristol furthermore operates an Ga2O3 MOCVD growth system providing device materials - in addition to processing AlGaN power devices you can also get involved in our Ga2O3 power device processing efforts. This position benefits from the Chair in Emerging Technologies awarded to Professor Kuball, Director of the CDTR, by the Royal Academy of Engineering (RAEng) in 2020, and the US Department of Energy funded ULTRA EFRC Center the CDTR is partnered in. This research position will give you the opportunity to make a major impact on future power device technology.

Applicants should have postgraduate (PhD) experience in physics, materials science or engineering, with a good publication record. The position requires extensive expertise in device processing, and a good understanding of device physics, as well as an interest in device simulations. A willingness to work together with, and co-supervise, PhD students of the CDTR will be necessary.

The position has funding for 2 years in the first instance.

Informal enquiries (not applications) to Professor M. Kuball,, tel +44(0)117 928 8734.

The University is committed to creating and sustaining a fully inclusive culture.  We welcome applicants from all backgrounds and communities, especially from women and other groups currently under-represented in our department.


Our school is home to 60 academic and 65 research staff, carrying out research spanning astrophysics, particle physics, quantum and soft matter, quantum engineering technologies, materials and devices and theoretical physics. We also have 170 postgraduate students and more than 600 undergraduate students enrolled in our extensive range of taught programmes, to which we are committed to providing an excellent learning experience and the highest standards of teaching.
