Welcome to my University web page. I am a senior lecturer in the School of Electrical and Electronic Engineering, having arrived in Newcastle in November 2002. I am a member of the Materials Modelling Group within Emerging Technology and Materials, with a research portfolio based on the first-principles simulation of defects in semiconductors, crystal surfaces, nano-structures and dielectrics, necessitating the use of parallel computing, some facilities for which are based here in Newcastle University.

Jonathan is a member of the Emerging Technologies and Materials research group, and his profile can be viewed on Google Scholar and ResearchGate.
My current research is primarily under a project entitled "Defect Engineering", which relates to the use of quantum-chemical methods to analyse dopants and other defects in crystalline materials to predict their optical, electronic and other properties.
Diamond, although strictly a very effective electrical insulator, may be modified to conduct electricity, with projected applications in fields from high-power switches to particle-detection. Pure diamond is optically transparent (in the visible part of the e-m spectrum) but defects in the crystal lattice can change the colour to bright yellows, red, pink, green and blue. Although these "fancy" diamonds occur naturally, they are very rare and hence expensive. However, defects giving rise to bright colour can be synthesized using high-pressure and temperature techniques, sometimes involving irradiation. The quantum-chemical simulation of defects formed in the crystal lattice informs us as to the potential origins of colour and other properties such as thermal stability, allowing the gemologists to determine with some degree of precision which diamonds have been artificially enhanced, or treated to increase their value.
The application and analysis of density-functional based quantum-chemical simulation programs also involves problems in visualisation.
Although I principally study diamond-based problems, I am simultaneously pursuing research in other materials: silicon-carbide, silicon, germanium, oxides (mainly STO, PTO, BTO and ZnO), III-V compound semiconductors and nano-structures.
I have a developing research interest in silicon and carbon based quantum structures for optical device application, as well as the role of surface functionalisation in such materials. Future research will also involve my interest in the quantum behaviour of light atomic species in solid solution.
