Electronic Structure and Properties of Defect Complexes in Metals
Abstract
Work has been confined to three different areas. These include: (i) Defect complexes - Interaction of hydrogen with vacancies, substitutional impurities, impurity-vacancy complexes, and lattice strain. Also studied are the interaction of He with metals, electric field gradient produced by impurities at host sites in cubic metals, positron annihilation in clean voids, as well as those containing rare-gas atoms and impurities, and the effect of lattice relaxation on the positron lifetime. (ii) Disordered Systems - Electronic states, magnetic behavior and the electrical transport in metal-metalloid glasses; role of metalloids in affecting the electronic spectrum; (iii) Clusters - Equilibrium geometries, stability, electronic structure, and properties of neutral and charged micro-clusters consisting of up to ten atoms. Keywords: Electronic structure, Defect complexes, Metals, Disordered systems, Clusters.
