Our mission

In today's fast-moving technological world, semiconductor devices need more ‘muscle power’ but today's devices run too hot, wasting energy and shortening operating lifetime. The CDTR mission is to develop a more energy-efficient semiconductor device technology, to reduce energy waste and boost the use of renewable energy to reach net zero goals.

The novel power devices we develop will provide improved energy efficiency at increasing voltage ranges, helping to meet the electrification demands of our society, and advance modern transport technology (electrical vehicle, train, maritime and aerospace). Higher power and higher frequency RF devices will also advance radar technology and telecommunications, with applications in 6G and beyond.

Our research

A main focus of our research lies in exploiting wide and ultra-wide bandgap semiconductors including GaN, Gallium Oxide, Boron Nitride and Diamond to develop next-generation power and RF devices. We are equipped with state-of-the-art material growth technology (metal organic chemical vapour phase deposition, MOCVD), we design new device topologies using TCAD and finite element modelling, process devices in-house, and implement advanced packaging solutions. We also apply a unique suite of techniques for device performance and reliability characterisation, as well as device electrical and thermal conductivity analysis.

Our team of more than 20 international researchers and PhD students works with industry and academia from across the globe. The CDTR also leads the flagship UKRI Innovation and Knowledge Centre (IKC) Transforming Net Zero with Ultrawide Bandgap Semiconductor Device Technology (REWIRE) whose 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, providing a vehicle for their commercialization.
