ELECTRONIC MATERIALS AND SEMICONDUCTOR DEVICES, essentially an outcome of the class-tested lecture notes of the author, attempts to present an account of the basic electronic properties of materials determined by their electrical, magnetic, dielectric, superconducting and semiconducting behaviours including brief introduction to the planar technology of semiconductor device fabrication at an introductory level, so that their applications in the design of electronic devices are easily understandable. The presentation in the book is lucid covering the fundamentals of the important Semiconductor Devices.

• • Short questions and worked examples at the end of each chapter
