Postdoc in GaN-AlGaN Electronic Device Thermal Imaging

Bristol (GB)
10 Nov 2021
14 Jan 2022

The role

This is a position in the Centre for Device Thermography and Reliability (CDTR), led by Professor Kuball, in the H.H. Wills Physics Laboratory and the School of Physics. The CDTR is a world-leading research centre focusing on transforming the electrical performance, thermal management and reliability of novel power electronic and RF electronic devices, circuits and packaging, made of/for wide and ultra-wide bandgap materials, such as GaN, Ga2O3, BN, AlN and diamond.

What will you be doing?

A particular focus of this position is to contribute to the development of a new (optically based) device thermal imaging technique which will allow nanometre scale determination of device temperature. The technique, once developed, will be applied to a wide range of devices ranging from nanowire transistors, very short gate length device technology, three dimensional superlattice castellated devices, in the field of wide and ultra wide bandgap materials/devices (GaN, AlN, diamond, Ga2O3). You will also have the opportunity to contribute to aspects of GaN-on-Diamond integrated materials and devices for ultra-high power RF electronics, as well as to materials and devices for >2-10kV power electronics applications e.g. in smart grids, for enabling energy savings towards a greener society. The work is aligned with 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.

You should apply if

Applicants should have postgraduate (PhD) or equivalent professional qualification or experience in physics, materials science or engineering,with a good publication record. The position requires expertise in TCAD device simulation, preferably Silvaco Atlas, and familiarity with RF and microwave devices. A willingness to work together with, and co-supervise, PhD students of the CDTR will be necessary.

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.
