Holes P-type semiconductors are created by doping intrinsic semiconductors with impurities that create an excess of holes.

It widens Reverse bias causes the depletion region to widen, effectively blocking the flow of current.

From P-side to N-side In forward bias, current flows from the P-side to the N-side because electrons and holes move towards the junction.

To act as a one-way switch for current A diode allows current to flow in only one direction, making it function like a one-way valve for current.

A PN junction diode The junction of P-type and N-type semiconductors creates the basic structure of a diode.
