Most generally a class of materials that are neither insulators or conductors in their natural state, but which can be manipulated via doping or electric fields to change their conduction state. Silicon, Germanium, and GaAs are some usual materials. The term is also used to speak about devices that are made from such materials, for example, a processor from Intel can be called a semiconductor.

Why do power diodes have a p+ n- n+ construction and why not p+ p- n+?
I've been learning about power diodes and how they differ from low power diodes with the addition of a lightly doped n-type layer.
This n-type layer improves the breakdown voltage rating of the devic …

How deep does the depletion region in power diode penetrate the lightly doped n- layer under...
I could find references for describing the depletion layer in a power diode under reverse bias and the consequent classification of Non-punch through and Punch-through diodes. But I couldn't find a s …

How does a MOSFET conduct in saturation region?
It is a simple question but I could not find a straightforward answer.
When a MOSFET enters saturation region, the channel length starts to decrease, and the channel width is the smallest near the d …
