Question

why is depletion region named so in a semiconductor diode? what is total charge of depletion region in a diode in forward biasing?​

Answer 1

Answer:

The depletion region is named so because it is formed from a conducting region by removal of all free charge carriers, leaving none to carry the current. The remaining holes will cross the depletion region and gets attracted to negative terminal of battery or terminate at the negative terminal of the battery. Thus, the positive charge carriers that are crossing the depletion region carry the electric current from one point to another point in the p-n junction diode.
