| Citation | Distinguished for his pioneering work in the application of surface science techniques to the study of semiconducting solids and important interfaces in solid state electronic devices. He is accredited internationally with developing the multi-technique approach to surface science within which the crystallography, chemical properties and electronic structure of semiconductors and associated metal overlayers are probed at the same time as their conventional electrical and optical properties. More specifically his novel experimental and theoretical work has resulted in a detailed understanding of the InP surface; his observations, showing how controlled intermediate layers of gas or metals can be used to modify metal-semiconductors interfaces, will be of lasting practical importance. He was the first to demonstrate that angle-resolved photoelectron spectroscopy could be used to determine the detailed electronic band structure of solids and also to appreciate the potential of synchrotron radiation as a probe for studying matter. His classic research, involving synchrotron radiation coupled with angle integral and angle resolved photoelectron spectroscopy, played a vital role in the development of Synchrotron Radiation Source at Daresbury. He has continued to provide inspirational leadership and exemplary administrative guidance in Science and Engineering Council initiatives in this field, His impressive list of over 100 papers also contains novel contributions in other fields of applied physics including photoluminescence, photovoltaic devices and adhesion. |
