Postdoctoral Researcher in GaN power devices

The role

The role is centred on the development of a novel vertical GaN-on-Si power transistor concept, and will involve device fabrication, material and device characterization and simulation. You will lead device development with a dedicated team of wide bandgap material and device experts toward fabrication of industry-relevant technology demonstrators with immediate impact in low carbon applications, including electric vehicles and renewable energy generation. You will also have the opportunity to present results to the wide range of industrial and academic partners who support the project across the power electronics supply chain. This research position will provide the opportunity to make meaningful impact on power electronics and low carbon technologies.

You will work in the Center for Device Thermography and Reliability (CDTR). The CDTR is a world-leading research center focusing on improving the electrical performance, thermal management, and reliability of novel semiconductor devices, and is active across many EU, US, and UK research programmes. It is funded by the UK Engineering and Physical Sciences Research Council (EPSRC), Royal Academy of Engineering (RAEng), the US Department of Energy, US Defense Advanced Research Projects Agency, the European Space Agency and other funding agencies as well as by industry.

What will you be doing?

You will develop vertical GaN transistors for power electronic applications using GaN material on non-native substrates (silicon, sapphire), supplied by project partners. This will include the development of device fabrication process modules in the state-of-the-art cleanroom in the School of Physics, toward integration into a high performance power device. You will characterize electrical and structural properties of devices in the world-renowned CDTR test lab, including reliability and failure analysis, and use TCAD simulation software to analyse the physical mechanisms underpinning device performance, ultimately toward optimization of device designs and fabrication processes. You will also be responsible for writing academic journal papers and attending conferences to present your work, in addition to liaising with project partners across academia and the power electronics industry.

You should apply if

Applicants should have postgraduate (PhD) experience in physics, materials science or engineering or working towards one, with a good publication record. The position requires expertise or interest in the development of novel electronic materials and devices, semiconductor device fabrication techniques and reliability analysis through use of materials/device simulation software. Cleanroom experience is required. A willingness to work together with, and co-supervise, PhD students of CDTR will be necessary.
