Under the umbrella of nitride semiconductors and devices, the book treats semiconductor fundamentals, technology, nanotechnology with clarity and depth not found elsewhere. The book is a combination of graduate level text book with all the necessary basis and derivations involving semiconductor and device physics and engineering, an extensive reference book for GaN and related material and ZnO, and a handbook for the same, all in one. Properties and processes with sufficient basis for thermal, optical (3, 2, 1, 0-dimensional systems), electrical (at low and high electric field, low and high magnetic field for 3- and 2-dimensional systems full with measurement techniques), magnetism and magnetic properties (in dilute magnetic ion doped varieties), spin based device concepts and associated measurement methods, semiconductor deposition methods, inclusive of hydride VPE, ogranometallic CVD, MBE, liquid/high pressure growth with fundamentals, extended defects and their electrical nature, point defects, and extensive discussion of doping, text book-like treatment of LEDs (including lighting and competing technologies), Lasers (including recording), FETs and HBTs (including novel treatment of fundamentals and hot phonon processes affecting the velocity), detectors and unique issues surrounding solar blind detection. The depth and scope of the book and the easily understandable treatment of subject matter are certain to lift any a-priori cloud present.
