Professor Richard Hogg

Chief Technical Officer

Professor Richard Hogg received his PhD in semiconductor physics from The University of Sheffield, specialising in III-V structures and materials. Richard was appointed as a researcher at NTT Basic Research Laboratories (Atsugi, Japan), conducting research on rare-earth doped semiconductors. He followed that with a year based at The University of Tokyo, Institute for Industrial Science, studying Sb based, self-assembled, quantum dots by MBE.

Richard returned to the UK working at Toshiba Cambridge Research Laboratories on a range of III-V semiconductor devices, before spending three years at Agilent Technologies, Ipswich. Agilent was, at that time, the highest volume III-V facility in Europe and Richard was responsible for wafer characterisation outputs on seven, MOCVD reactors, developing and manufacturing InP and GaAs optical components.

He is now head of The Electronic and Nanoscale Engineering Division at the University of Glasgow, and is actively involved with a number of high-growth photonics companies.

Dr. Neil Gerrard

Director of Epitaxy

Dr. Neil Gerrard is a well-respected III-V epitaxial engineer and director, with over thirty years’ industrial experience. Neil has extensive III-V, compound semiconductor manufacturing experience in wafer FAB and Epitaxy operations.

Neil was Technical Marketing Director at Aixtron UK Ltd (Thomas Swan); UK MD at LayTec UK; and engineering lead in start-ups, KUBOS and Optical Reference Systems. Neil helped set up and run the wafer fab at Nortel Networks and the MOCVD facility at Sivers. Neil was also Director of Operations and Business Development for the Engineering and Physical Sciences Research Council (EPSRC), where he first worked with fellow director, Prof. Richard Hogg. Here he helped set up the National Centre for III-V Technologies at The University of Sheffield.

Neil has a PhD from the University of Manchester, Institute of Science and Technology (UMIST). He followed this with post-doctoral research at Bell Labs.
