Applications are invited for the role of Postdoctoral Researcher position at the Centre for Device Thermography and Reliability (CDTR), led by Professor Kuball, to provide leading contributions in the field of Gallium Oxide device processing, device modelling and characterization. This is a one-year position, initially.

Gallium Oxide has attracted great attention for the next generation of power electronics for its performance advantages over existing wide bandgap semiconductor materials. You will have access to state-of-the-art, in-house, MOCVD grown Gallium Oxide material, a state-of-the-art clean room and advanced electrical (up to 10kV), reliability and thermal characterisation techniques. Prior experience in Gallium Oxide processing is strongly preferred for this proposition. You will also interact with the UKRI funded Innovation and Knowledge Centre (IKC) REWIRE, which works on developing and commercializing next generation power electronics

REWIRE’s aim is to accelerate the UK’s ambition for net zero by transforming the next generation of high voltage electronic devices using wide/ultra-wide bandgap compound semiconductors. In addition to REWIRE, this position also benefits from the CDTR leading the EPSRC programme grant ULTRAlGaN on developing vertical solid state circuit breakers using high composition AlGaN materials and the Chair in Emerging Technologies awarded to Professor Kuball, Director of the CDTR, by the Royal Academy of Engineering (RAEng) in 2020, and various US funded programmes the CDTR is partnered in.

What will you be doing?

You will conduct research to develop advanced ultrawide bandgap semiconductor device technology and their understanding. Responsibilities include the processing of high-voltage power devices, in particular, Ga[2]O[3], conducting electrical characterization and testing of the processed devices and performing simulations of targeted device structures.

You will supervise/advise Senior Cleanroom technician and work together with/co-supervising PhD students of CDTR.

Applicants should have postgraduate (PhD) experience in physics, materials science or engineering, or be working towards one, ideally with a good publication record. The position requires extensive expertise in sophisticated techniques such as electron beam and/or photolithography, reactive ion etching, atomic layer deposition and associated cleanroom activities. A willingness to work together with, and co-supervise, PhD students of the CDTR will be necessary.
