What is P-type semiconductor?
What is P-type semiconductor? when a small amount of trivalent impurity is added to a pure semiconductor, it is called p-type semiconductor. The addition of trivalent impurity provides a large number of holes in the semiconductor. Trivalent impurities: Gallium, Indium, Boron ,Aluminum The impurities which produces p-type semiconductors are known as acceptor impurities because the … Read more
