P-type Semiconductor

A P-type semiconductor is a material that has been intentionally infused with impurities (called doping) to create an abundance of positive charge carriers known as "holes." These holes act like positive particles that can move through the material and conduct electricity. In P-type semiconductors, the majority carriers are holes, while electrons are the minority. This modification allows the semiconductor to control electrical current, essential in devices like diodes and transistors. Essentially, P-type semiconductors are designed to have more positive charge carriers than negative ones, enabling specific electrical properties useful in electronics.
