Solid State Devices

Designed as a text for undergraduate students of engineering in Electrical, Electronics, and Computer Science and IT disciplines as well as undergraduate students (B.Sc.) of physics and electronics as also for postgraduate students of physics and electronics, this compact and accessible text endeavours to simplify the theory of solid state devices so that even an average student will be able to understand the concepts with ease. The authors, Prof. Somanathan Nair and Prof. S.R. Deepa, with their rich and long experience in teaching the subject, provide a detailed discussion of such topics as crystal structures of semiconductor materials, Miller indices, energy band theory of solids, energy level diagrams and mass action law. Besides, they give a masterly analysis of topics such as direct and indirect gap materials, FermiDirac statistics, electrons in semiconductors, Hall effect, PN junction diodes, Zener and avalanche breakdowns, Schottky barrier diodes, bipolar junction transistors, MOS field-effect transistors, Early effect, Shockley diodes, SCRs, TRIAC, and IGBTs. In the Second Edition, two new chapters on opto-electronic devices and electro-optic devices have been added. The text has been thoroughly revised and updated. A number of solved problems and objective type questions have been included to help students develop grasp of the contents. This fully illustrated and well-organized text should prove invaluable to students pursuing various courses in engineering and physics. Distinguishing Features Discusses the concepts in an easy-to-understand style. Furnishes over 300 clear-cut diagrams to illustrate the concepts discussed. Gives a very large number of questionsshort answer, fill in the blanks, tick the correct answer and review questionsto sharpen the minds of the reader. Provides more than 200 fully solved numerical problems. Gives answers to a large number of exercises.
