Abstract : In this final technical report we summarize the activity carried out within the present research project, conducted over a three year period, under the sponsorship of the European Research Office of the U.S. Army. The work done covers different areas, namely: (1) Microscopic simulations of solid, amorphous and liquid semiconductors and semimetals, of their defects, vacancies, and surfaces, and of hydrogen diffusion, using Car-Parrinello and related methods; (2) Theory of the electronic and vibrational properties of semiconductors, semiconductor alloys, interfaces, microstructures, and of GaAs - based semiconductor superlattices; (3) Quantum simulations and theory of highly correlated electron systems particularly as models for high-T (sub c). superconducting materials; The body of the report will briefly outline the work done in each area, and highlight the main achievements which have been made possible by the project.
