| Citation | Distinguished for his work on the theory of the defect solid state, and particularly for advances in quantitative understanding of defect processes and of the electronic structure of defects. He pioneered the use of self-consistent methods for defects and impurities in ionic crystals (both bulk and surface defects), semiconductors and metals, and the application of pseudopotential methods to ionic crystal defects (c.f. the Bartram-Stoneham-Gash ion-size corrections). He has analysed the effects of electron-lattice coupling on defect spectra, stability and dynamics, including diffusion, non-radiative transitions and recombination-enhanced diffusion, and the picosecond photolysis mechanism in alkali halides. He has predicted the statistical distributions of random fields produced by defects, widely applied in spectroscopy, and has identified the mechanisms controlling the observed long range order in heavily-irradiated and highly non-stoichiometric crystals. The diffusion of light interstitials, like hydrogen in metals, has been illuminated by the Flynn-Stoneham quantum theory treatment. His book on "The Theory of Defects in Solids" represents a seminal contribution to the literature in this field. His technical imagination and flexibility have also been demonstrated by important contributions to several commercial programmes at Harwell, e.g. he and his group contributed substantially to the theory underlying the on-line non-destructive testing by ultrasonics of gas pipe lines. |
