Research Interests

I have been has been studying the infrared and THz properties of silicon-based materials and devices for 12 years. My 2002/2003 papers on THz intersubband electroluminescence from SiGe quantum cascade structures, were world-firsts and are the most highly cited works in the field.

I also demonstrated the first electroluminescence from shallow impurities in silicon, and their potential for electrically pumped silicon THz lasing. I was deeply involved with the first experimental measurement of phosphorus donor lifetimes in 2008, and my 2010 Nature paper represents a breakthrough in the field of silicon-based quantum computing.

My most recent work shows that the incorporation of a small amount of germanium in the silicon single crystal matrix allows the energy level structure of the phosphorus donors to be engineered without any detrimental effect on the lifetime dynamics of the phosphorus donor, and hence on its potential quantum applications.

Measures of Esteem

I am a currently a Senior Member of the IEEE. I have been a member of the EPSRC College since 2008, and I have served several EPSRC Panels from 2010. I chaired one of the EPSRC ICT Panels in 2013. I have served on the Royal Academy of Engineering Sift Panel for Research Fellowships for 2010 and 2011. I have served on the 2011 IEEE Panel for elevation to Senior Member level.

Biography

I am Senior Lecturer at the School and formerly an EPSRC Advanced Research Fellow. I am also a visiting Associate Professor at the University of Warwick, and an honorary Senior Lecturer at University College London.

My postdoctoral research career began on joining Prof Sir Mike Pepper’s group at the Cavendish Laboratory, at the beginning of 2000, following the successful defense of my PhD at Trinity College Dublin. I was subsequently elected to a Research Fellowship at St Edmund’s College, Cambridge, in 2002. During this time I worked on the development of far-infrared (THz) SiGe quantum cascade devices.

In 2007 I joined the London Centre for Nanotechnology at University College London, working first under the late Prof Marshall Stoneham FRS, and later Prof Gabriel Aeppli FRS. I was awarded an EPSRC Advanced Research Fellowship to work on the physics of far-infrared emission from impurity doped semiconductors later that year.

I moved to the Department of Physics and Astronomy at Cardiff University in May 2011.

In addition to my academic roles, I am a Consultant Technical Advisor for London based company ‘Bio Nano Consulting’. The company facilitates the development and commercialisation of new biomedical and nanotechnology-based techniques and products. I am also a Consultant Technical Advisor for Irish company ‘Technology From Ideas Ltd.’ The company offers academics a zero cost way of easily and quickly commercialising their ideas without the difficulties of developing the technology themselves.
