The four-layer diode, also known as a Shockley Diode, is a crystal made of alternating layers of N- and P- type semiconductors. By putting in four layers, instead of the three used in transistors ...

Specifically you will learn: a) types of semiconductors that are of interest and ... The minority carrier charge and its effect on switching losses, and d) The construction of a p-n diode SPICE model ...
