Summary
The course "Materials for Electrical Engineering" represents a general basis for studies and it provides to students an overview of materials that are used at designing of various electrical, opto-electronic and micro-electronic devices. It deals namely with electrical, magnetic, physical-chemical, mechanical and other properties of substances and it puts them into relation with composition and internal structure of materials. The course also focuses on the processes of preparation of individual kinds of materials by current technologies related to electronics and micro-electronics, used materials and trends associated with the miniaturisation of electronic systems. Explanation of electrical materials will be conducted according to the scheme: Structure and properties of materials, conductive materials, super-conductors, semi-conductors, micro-electronics and opto-electronics, magnetic materials, dielectric and insulating materials and special structural materials.
