Introduction to Semiconductor Diode

• The two types of extrinsic semiconductors are n‒type and p‒type.

• In n‒type, the electrons are majority charge carriers while holes are minority charge carriers.

• In p‒type, the holes are majority charge carriers and electrons are minority charge carriers.

• These two types of materials namely n‒type and p‒type are chemically combined with a special fabrication technique to form a p‒n junction. Such a semiconductor p‒n junction forms a popular electronic device called diode.

• In a p‒n junction on p side there are large number of holes while on n side there are large number of free electrons. Hence overall p‒n junction acts as nonuniformly doped material.
