2nd Semester ECE

The English language course aims at familiarising students with language use in a variety of social contexts and communicative tasks (development of linguistic awareness). A range of practical activities in different grammatical and syntactic structures are regularly provided along with activities designed to develop understanding and production of both spoken and written language. The level attained at the end of the semester is B2, as it is defined by the Common European Framework of Reference for Languages.

- Introduction to quantum mechanics. Schrödinger's equation. Quantum mechanical tunneling and applications. - The creation of energy zones/bands, the classification of materials according to their energy gap. - Crystal structures. Ideal, real. Crystal defects. Diamond crystal structure. The effects of crystal defects on the potential energy graphs (energy gap levels, surface energy levels). - Distribution functions. Fermi-Dirac statistics. Concentration, mobility of charge carriers, scattering, and effective mass of electrons-holes. Conductivity in semiconductors. - Classical and quantum mechanical transport phenomena: Drift - diffusion and tunneling phenomena – thermionic emission. - Interaction of light and semiconductors. Photon absorption and recombination. Radiant and non-radiant recombination (between Auger-type bands, and deep electronic states). - The continuity equation. - Semiconductor metal contact (Schottky diode, ohmic contacts). p-n diode
