"Electrical Engineering Materials" covers the area of quantum mechanics that leads to the understanding of electrical behaviour of materials. The classification of material is based on energy band structure. This book clarifies that the conductivity of material is determined by mobile charge carrier concentration and drift mobility and the reasons for higher conductivity in metals and lower conductivity in semiconductors. The book also covers dielectric materials: polarization mechanism, temperature and frequency dependence, piezoelectricity and ferroelectricity. Starting from the elementary concepts associated with magnetism and latest developments in magnetic materials, it explains the concept of semiconducting material, their characteristics and formation of p- and n-type semiconductors. Similarly, the behaviour of pn junction under different bais voltages are described as also the principle of semiconductor material fabrication, purification of Si, doping mechanisms, the device fabrication along with different aspects associated with superconductivity, types of superconducting materials with update on latest development in the field of superconductivity.
