Center for Device Thermography and Reliability

Probing RF properties of GaN-based devices

The Center for Device Thermography and Reliability (CDTR), led by Professor Martin Kuball is a world-leading research center focusing on improving the thermal management, electrical performance and reliability of novel devices, circuits and packaging.

Why do we exist?

In today's fast-moving technological world, semiconductor devices need more ‘muscle power’, but devices must not overheat.

It is projected that the next generation of wireless architecture (5G) will increase data communciation speeds to multiple times that of existing 4G. Semiconductors enable this wireless architecture. Today's devices run too hot, wasting energy and giving them a short operating life time.

Furthermore, if we use today’s technology, by 2035 the planet’s datacentres will cover 6 x the land area of the M25 and use over 40% of global energy production.

Artificial Intelligence (AI) will become the biggest single contributor to climate change. Better semiconductors can help mitigate this.
The world needs new devices which are more energy efficient, that can also run at high powers. This is what we aim to achieve in the CDTR.

To achieve this goal, since 2001 we have been developing and applying new techniques for temperature, thermal conductivity, electrical conductivity and traps analysis, especially for microwave and power electronic semiconductor devices, made of wide bandgap materials, such as GaN, SiC, Gallium Oxide and diamond. Our team of about 20 international researchers and PhD students works with industry and academia from across the globe to develop the next generation of technology for communications, microwave and power electronics to enable the low carbon economy.


Join us!

Join us for the co-located 44th Workshop on Compound Semiconductor Devices and Integrated Circuits held in Europe (WOCSDICE) and 15th Expert evaluation and Control of Compounds of Semiconductor Materials and Technologies (EXMATEC) in Bristol, United Kingdom in 2020!

‚ÄčThese two long-established and complementary workshops in compound semiconductor devices and materials will once again be held jointly, this time in the vibrant and exciting city of Bristol.
