Our research and our partnership with a compound semiconductor facility has led to the world’s first Compound Semiconductor Cluster and investment of over £167 million.

Compound semiconductors underpin the next generation of opto-electronic devices, but the UK has lacked an end-to-end compound semiconductor industry. For some years researchers in the School of Physics and Astronomy have been engaged in developing methods for the improved design, production and characterisation of compound semiconductors. This has resulted in more efficient manufacturing processes and quality control. As a result, a research partnership developed between compound semiconductor manufacturer, IQE, and researchers at Cardiff. This strategic partnership and IQE’s decision to expand its manufacturing base, and to maintain its headquarters in Wales, resulted in the foundation of the world’s first Compound Semiconductor Cluster which has led to investment of over £167 million.
