The role
Applications are invited for the role of Postdoctoral Researcher at the Centre for Device Thermography and Reliability (CDTR), led by Professor Martin Kuball.
This role encompasses the design, fabrication and characterization of wide and ultra-wide bandgap semiconductor materials and devices, including GaN, Ga2O3, SiC and diamond (key enabling materials for power and RF electronics). Examples of interest include vertical GaN power transistors on native and non-native substrates, AlGaN-based high power devices and N-polar AlN-based devices. You will have the opportunity to develop and study unique device structures, and to access the extensive electrical device testing suite available in Bristol, in addition to thermal and electric field analysis of devices, and simulation tools (Silvaco Victory/ATLAS, ANSYS). You will also have access to a state-of-the-art Cleanroom and the opportunity to collaborate within our 35-member team as well as with our industrial partners spanning the semiconductor supply chain.
The CDTR leads/contributes to numerous UK and international strategic programmes on power and RF electronics, including ESA programme S2CANT, EPSRC programme grant ULTRAlGaN and the £11M UKRI Innovation and Knowledge Centre REWIRE, focusing on GaN, Ga2O3, SiC and diamond power materials and devices, from their fundamental understanding/development, to commercialization of device technology, in part co-designed with industry. This position also benefits from the Chair in Emerging Technologies awarded to Professor Kuball by the Royal Academy of Engineering (RAEng) in 2020, and various US funded programmes the CDTR is partnered in. You will have the opportunity to make a major impact on future semiconductor device technology.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What will you be doing?
You will advance wide and ultra-wide bandgap semiconductor materials device technologies and its understanding.
- Responsibilities include the fabrication/processing of power semiconductor devices in the cleanroom using advanced fabrication techniques, and the electrical characterization of wide and ultra-wide bandgap materials.
- You will develop TCAD models to complement experiments, support device design and to analyse device failure, breakdown and reliability.
