Current Research Interests
My research interests in the field of Theoretical Solid State Physics are: the study of the properties and phenomena of solids with the help of quantum mechanics and other approximate approaches. The properties include the electronic structure, optical, electrical, basic state, metastable states, equilibrium positions of atoms, geometry of structures and their change under external influences such as temperature, mechanical stresses and strains for metals, insulators and semiconductors. The structures can be crystalline, surfaces, defects, extended defects, and nanostructures as elements, compounds, and alloys. Current research interests also include composite systems and systems for nanometrology.
My research interests in the field of Didactics are: the design and study of interventions and appropriate educational materials for the teaching of Physics, Materials and Metrology at all levels of formal and informal education, adult education and teacher training. Methodologies can be: synchronous interactive teaching, distance learning, experiments and remote experiments, simulations, educational software, interactive web sites, and informal education.
