| 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. |
| Learning Outcomes of the Course Unit |
|---|
Student will be able to:
- classify basic groups of the current and advanced materials for applications in electric engineering, micro-electronics and opto-electronics
- apply basic theoretical knowledge on influence of composition and internal structure of material on physical, mechanical, electrical, magnetic and optical properties
- define requirements for individual groups of materials, technology for preparation and further processing, realisation of electronic elements |
