The CS Hub investigators and associated groups have been carefully selected for their track record in innovation and impact, complementary technical capability and the individual skill sets that can combine to create new solutions to the identified major scientific challenges in manufacturing.
In Brief: All 5 universities have outstanding and complementary CS research and world leading facilities, with comprehensive technician and engineering support. Together we can do research on all the important semiconductors with respect to epitaxial-growth, fabrication, characterisation, component and integrated circuit design and systems for applications development: e.g. Cambridge provides 200mm (8”) MOCVD for III-N growth; UCL provides a unique III-As, III-P and III-Sb and Si MBE facility; Cardiff  provides MOCVD for III-P, III-Sb and III-As on silicon. Manchester provides electronic circuit design; Manchester, UCL and Cardiff provide characterization capability including RF on wafer to 110GHz, Electro-Optic component analysis to 67GHz and bit error rate testing to 100GBit/s. In CU the ICS supports our vision for researchers to work alongside industry staff using manufacturing equipment. The 1350m cleanroom has a 200mm CS fabrication line alongside research scale equipment with similar operating principles. Our partners, such as the CSA Catapult, IQE, OIPT, Teledyne and Renishaw also have world leading specialist facilities.
Prof Peter Smowton (Cardiff University) is Director of the EPSRC Future Compound Semiconductor Manufacturing Hub, is one of four Directors of the Institute for Compound Semiconductors (currently Managing Director). He is well connected internationally having had program and general chair roles in the sector leading CLEO and ISLC conferences and as a leading member of the IEEE Photonics Society. His expertise is in compound semiconductor materials, device design, characterisation and integration. He works closely with companies such as IQE, Oclaro and Renishaw and in 2017 won the Insider Individual Impact Business and Education Partnership Award .


Professor Lenny Koh, BEng (Hons), PhD, FRSA, (University of Sheffield) is a Chair Professor in Operations Management, Founders and Directors of the Logistics and Supply Chain Management (LSCM) Research Centre at the Management School & the Faculty’s Centre for Energy, Environment and Sustainability (CEES), at The University of Sheffield, UK. She is also the co-founder of Supply Chain Management and Information Systems (SCMIS) Consortium, a global network of leading academic and practitioners driving research and knowledge exchange on supply chain and information systems. A World leading mind recognised amongst FRSs and Nobel Laureates within the University, Professor Koh is a Senior Chair Professor, an internationally renowned and established authority in supply chain especially on low carbon and sustainability, with a high H-index (World number 2) and high research income generation in her discipline internationally. She is active in leading a 2022 Futures initiative advancing resource efficiency and supply chain disciplines, navigating a new translational model for connecting invention/basic science at lower TRL to higher TRL.


Prof Rachel Oliver ( University of Cambridge) is Director of the Cambridge Centre for Gallium Nitride, Prof Oliver’s research interests focus on the characterization and exploitation of nanoscale structures in GaN-based materials. The broad aim of my work is to achieve improved performance in GaN-based electronic and optoelectronic devices and to develop and implement novel device concepts.  Cambridge is also the main supplier of nitride epitaxy in the EPSRC National Epitaxy Facility (NEF), and provides nitride materials to academics across the UK


Prof Paul Tasker (Cardiff University) leads the university EPSRC “Integration of RF Circuits with High Speed GaN Switching on Silicon Substrates” and the EPSRC “High Performance Buffers for RF GaN Electronics” grants, both of direct relevance to the hub. His expertise is in high frequency design, fabrication and characterisation including development of a MMIC technology platform. He works closely with industry (e.g. Nokia, Cree, MAcom, Selex, QinetiQ), has 4 patents on non-linear RF measurement and co-founded spin out company Mesuro Ltd (revenue > £2.5M and acquired by Focus Microwaves in 2015).
Prof David Wallis holds a joint chair in compound semiconductors at the universities of Cardiff and Cambridge and is a EPSRC Manufacturing fellow. His expertise is in the growth and Characterisation of III-V semiconductor materials. For most of his career he has worked in industry and between 2011 and 2015 lead the transfer of GaN on Si growth technology from a university spin out to Plessey Semiconductors. He is also currently treasurer for the UK Nitrides Consortium and helps to organise the UKNC annual conference which attracts more than 100 researchers in the field of Nitrides.
Prof Mohamed Missous FREng (University of Manchester) is Professor of Semiconductor Materials and Devices. His expertise includes Molecular Beam Epitaxy of Arsenides and ultra-high sensitivity sensors with a track record in developing manufacturable processes and technology transfer e.g. commercialisation by e2V Ltd of 77GHz Gunn diodes for Cruise Control systems in BMW and Audi cars. He leads an STFC, Innovate UK and EPSRC (£2M) programme in CS Sensors. He is founding director of two spin out companies (Advanced Hall Effect Sensors and Integrated Compound Semiconductors Ltd) and received the 2014 Royal Society Brian Mercer award for Innovation.
Prof Huiyun Liu (UCL) is Chair of Semiconductor Photonics. He first demonstrated Quantum Dot (QD) lasers on Ge substrates; 1300-nm QD laser on Si substrate; III-V/Si laser with >100,000 h lifetime and has >300 papers including record low threshold current density for multi-layer CS QD lasers. He is currently leading the CS epitaxial growth on silicon for 3 relevant EPSRC grants, “Energy and the Physical Sciences: Semiconductor III-V QD Solar Cells on Silicon Substrates”, “Silicon based QD light sources and lasers”, and “Nanoelectronic Based Quantum Physics- Technology and Applications”. He works with industry, including Huawei, Oclaro, DSTL, Sharp, IQE and Total. He has 3 patents and is co-founder of spin out company, Gasp Solar, a maker of CS on Silicon solar cells.
These staff are supported by academics Max Migliorato (University of Manchester), Jiang Wu (UCL), Roberto Quaglia (Cardiff University) and Senior Research Fellows Siming Chen (UCL), and Sang Soon Oh (Cardiff University) covering design, nitride fabrication, RF electronics and characterisation and growth of CS on Si.
