Advanced Semiconductor Fundamentals, Second Edition, by Robert F. Pierret is an advanced level presentation of the underlying functional formalism routinely used in describing the operational behavior of solid state devices. The second edition provides an update of the topic presentation, semiconductor parametric information, and relevant references throughout the volume. There is also a 50% increase in the end-of-chapter problems. Given the success of the first edition, the second edition retains the same overall material coverage and a pedagogical approach in introducing necessary concepts, models, and formalism.
