The role

Applications are invited for the role of Postdoctoral Researcher in the School of Physics, Centre for Device Thermography and Reliability (CDTR), to contribute to the advancement of wide bandgap and ultra-wide bandgap semiconductor materials and devices (power electronics, RF electronics including SAW devices).

What will you be doing?

A particular focus of this position is to contribute to the understanding/optimisation of thermal management and reliability of these devices. You will have the opportunity to lead the development and application of a new (optically based) and unique device thermal imaging technique which will allow nanometre-scale determination of device temperature (beyond the common optical spatial resolution limit). You will also be involved in the development of high spatial resolution femto-second laser-based techniques to study electric field effects and stress/strain fields which impact device reliability. You will use these techniques to study very advanced device technology (made available to us from academic and industry collaborators, also in-house Ga2O3 fabricated devices) from nanowire transistors, ultra-scaled HEMT device technology, three dimensional superlattice castellated devices, in the field of wide and ultra-wide bandgap materials/devices (GaN, Ga2O3). The work 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 and RF device technology.

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

You should apply if

Applicants should have postgraduate (PhD) experience in physics, materials science or engineering, with a good publication record. The position requires expertise or interest in the development of thermal and optical measurement techniques and their application to electronic materials and devices, as well as an interest in materials/device simulation. A willingness to work together with, and co-supervise, PhD students of CDTR will be necessary.

For informal enquiries please contact Professor Martin Kuball (Martin.Kuball@bristol.ac.uk).

We welcome applications from all members of our community and are particularly encouraging those from diverse groups, such as members of the LGBT+ and BAME communities, to join us.
