Discusses conducting material, semi-conducting material, insulating material and magnetic material. It also contains material for electronic components describing IC fabrication. Some advanced topics like materials for MHD generator, LASER and fiber-optic etc. and special purpose materials such as nano-material, optical material, nuclear engineering material and material for space applications have also been covered in the text. Each concept has been discussed with a number of solved problems, objective type and short answer type questions at the end of each chapter.
