The newly formed Institute for Compound Semiconductors and the Sêr Cymru group form part of a £300m investment in new research and innovation centres.

The Institute will be a unique facility in Europe, equipped with state-of-the art fabrication, epitaxy and device characterisation facilities. Stimulated by demand for a creative and professional prototyping service, the Institute provides an environment to advance academic research towards industrially-facing projects and is a foundational member of the Compound Semiconductor Cluster.

Its potential is already recognised by the Welsh and UK governments, who have invested over £29m towards its creation.

Molecular Beam Epitaxy (MBE)

Cardiff University is now equipped with two state-of-the-art Veeco Gen930 R&D MBE reactors, based within the School of Engineering. One reactor is capable of arsenide/antimonide epitaxy, while the other is devoted to nitrides epitaxy. Both systems have now been installed in a well-equipped facility and are ready to be calibrated using available ultra-high purity material sources.

Metalorganic chemical vapour deposition (MOCVD)

An AIXTRON Flip Top CCS MOCVD system has been installed and recently commissioned in a class 10,000 reactor room, dedicated to III-As, III-P, and III-Sb growth on Si and III-V substrates. The unique Close Coupled Showerhead (CCS) design allows an intrinsically uniform and reproducible growth for all the material systems of interest and provides a highly flexible process window for the deposition of a wide range of nano-structures (layers, fins, dots, wires). This MOCVD R&D tool is equipped with a high temperature (up to 1300°C) three-zones resistive heater, required to prepare the silicon substrate for the subsequent growth of high crystalline quality III-V layers. A multi-channel pyrometer consisting of a photodiode array will allow real-time surface temperature monitoring for a better control of the alloy composition and the optoelectronic properties of the deposited structures.

Optical Laboratory

The optical laboratory is situated within the School of Physics and Astronomy. It aims to deliver integrated and functional photonic devices by utilising novel nanostructures and metamaterials. The well-equipped lab provides an outstanding environment to test and characterise devices, and perform cutting-edge research into photonic applications.
