Summary

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.
