#### Abstract

This set of lecture notes is intended to help students learn the basics of PN junction theory and modeling. The following topics are covered: equilibrium analysis of step junctions and linearly-graded junctions, ideal current-voltage (I-V) characteristics, generation and recombination currents in non-ideal diodes, and the numerical analysis of PN junctions.

This series is a set of materials formerly known as a "Learning Module." The presentations are meant to be viewed in sequence to get a full understanding of the topic. Please click on the following links in order to access each of the presentations in sequence.
