£11m semiconductor research centre could be key player in UK’s net zero mission

February 13, 2024

The IKC will accelerate the UK’s ambition for net zero by transforming the next generation of high-voltage electronic devices using wide/ultra-wide bandgap (WBG/UWBG) compound semiconductors. The centre will advance the next generation of semiconductor power device technologies and enhance the security of the UK’s semiconductor supply chain. Compound semiconductor WBG/UWBG devices have been recognised in the UK National Semiconductor Strategy as key elements to support the net zero economy through the development of high voltage and low energy-loss power electronic technology. “Power devices are at the centre of all power electronic systems and pave the way for more efficient and compact power electronic systems, reducing energy loss,” said Kuball. REWIRE is one of two new IKCs announced being funded by the Engineering and Physical Sciences Research Council (EPSRC) and Innovate UK, both part of UK Research and Innovation.

Semiconductors, also known as microchips, are a key component in nearly every electrical device from mobile phones and medical equipment to electric vehicles.

They are increasingly being recognised as an area of global strategic significance due to the integral role they play in net zero, AI and quantum technology.

Co-created and delivered with industry, the REWIRE IKC is led by the University of Bristol, in partnership with Cambridge and Warwick Universities.

The IKC will accelerate the UK’s ambition for net zero by transforming the next generation of high-voltage electronic devices using wide/ultra-wide bandgap (WBG/UWBG) compound semiconductors.

The project is being led by Professor Martin Kuball and his team at the University of Bristol. Cambridge members of the IKC team include Professors Rachel Oliver, Florian Udrea and Teng Long.

The centre will advance the next generation of semiconductor power device technologies and enhance the security of the UK’s semiconductor supply chain.

Compound semiconductor WBG/UWBG devices have been recognised in the UK National Semiconductor Strategy as key elements to support the net zero economy through the development of high voltage and low energy-loss power electronic technology.

They are essential building blocks for developing all-electric trains, ships and heavy goods electric vehicles, better charging infrastructure, renewable energy and High Voltage Direct Current grid connections, as well as intelligent power distribution and energy supplies to telecommunication networks and data centres.

“Power devices are at the centre of all power electronic systems and pave the way for more efficient and compact power electronic systems, reducing energy loss,” said Kuball. “The REWIRE IKC will focus on power conversion of wind energy, electric vehicles, smart grids, high-temperature applications, device and packaging, and improving the efficiency of semiconductor device manufacture.”

Our home electrical supply is at 240 Volts, but to handle the power from offshore wind turbines, devices will have to operate at thousands of Volts. These very high voltages can easily damage the materials normally used in power electronics.

“Newly emerging ultra-wide bandgap materials have properties which enable them to handle very large voltages more easily,” said Oliver, who Director of the Cambridge Centre for Gallium Nitride. “The devices based on these materials will waste less energy and be smaller, lighter and cheaper. The same materials can also withstand high temperatures and doses of radiation, which means they can be used to enable other new electricity generation technologies, such as fusion energy.”

“The REWIRE IKC will play a prominent role within the UK’s semiconductor strategy, in cementing the UK’s place as a leader in compound semiconductor research and development, developing IP to be exploited here in the UK, rebuilding the UK semiconductor supply chain, and training the next generation of semiconductor materials scientists and engineers,” said Professor Peter Gammon from the University of Warwick.

Industry partners in the REWIRE IKC include Ampaire, BMW, Bosch, Cambridge GaN Devices (CGD), Element-Six Technologies, General Electric, Hitachi Energy, IQE, Oxford Instruments, Siemens, ST Microelectronics and Toshiba.

REWIRE is one of two new IKCs announced being funded by the Engineering and Physical Sciences Research Council (EPSRC) and Innovate UK, both part of UK Research and Innovation. The second IKC at the University of Southampton will improve development and commercialisation of silicon photonics technologies in the UK.

“This investment marks a crucial step in advancing our ambitions for the semiconductor industry, with these centres helping bring new technologies to market in areas like net zero and AI, rooting them right here in the UK,” said Minister for Tech and the Digital Economy Saqib Bhatti. “Just nine months into delivering on the National Semiconductor Strategy, we’re already making rapid progress towards our goals. This isn’t just about fostering growth and creating high-skilled jobs, it's about positioning the UK as a hub of global innovation, setting the stage for breakthroughs that have worldwide impact.”
