Review of Diode Physics and the Ideal (and Later, Nonideal) Diode
Abstract
The basics of bipolar devices are covered, including basic semiconductor physics; the concepts of electron and hole flow in semiconductors; the differences between drift and diffusion flow, generation, and recombination; and the effects of semiconductor doping on carrier concentrations. We finish with a discussion of the ideal diode and illustrate how a diode not only can conduct forward current but also can block reverse voltage. Detailed mathematical derivations are avoided wherever possible. However, enough mathematical detail is given so that the reader can discern the important scaling laws and functional dependencies of the ideal diode. At the end of the ...
