This textbook presents a detailed description of basic semiconductor physics, covering a wide range of important phenomena in semiconductors, from simple to advanced. It introduces and explains four different methods of energy band calculations in the full band region and covers fundamental topics such as the effective mass approximation and electron motion in a periodic potential, the Boltzmann transport equation, and deformation potentials used for the analysis of transport properties. The text also examines experimental and theoretical analyses of cyclotron resonance in detail and reviews...
