The goal of this course is to develop an understanding of the physics and properties of semiconductors. We will discuss crystal structure, quantum mechanics, quantum-confined structure, energy bands, electrons and holes, statistics, density of states, Fermi level, carrier concentration, carrier transport phenomena and current, carrier generation and recombination, and Hall effect.
