The aim of teaching of the subject is to provide students with basic information about current and prospective materials, which are used in various fields of electrical engineering and micro-electronics. Individual categories of materials for applications in electrical engineering are the following ones: conductive materials (conductors, super-conductors, materials for contacts, thermo-electric conversion, resistance materials, solders), dielectrics, ferro-electric materials and insulating materials, magnetic materials (soft, hard, special - based on alloys of rare-earth metals and oxides) semiconductors for micro- and opto-electronics, solar cells, metallic glasses, liquid crystals, nano-materials.The subject is oriented on characterisation of the processes for preparation of individual types of materials by the existing technologies in relation to micro-electronics, used materials and directions of development for the needs of qualified solution of problems connected with continuing miniaturisation of electronic systems and elements. Considerable attention is paid to semi-conductors and integrated circuits with very high integration, to the impact of geometric dimensions on properties of solid materials, to the influence of non-equilibrium processes on the formation of micro-structure, to the principles of selectivity and to the procedures of micro-technological operations using synthesis, forming of micro- and nano-layers, their characterisation, properties and applications in electronics. Lectures on theory of synthesis of materials, molecular engineering and micro-technologies will give an idea about technologies of next decades.
