P-टाइप
P-टाइप, or P-type semiconductor, is a type of material that has been doped with elements that create "holes" or positive charge carriers. This is typically achieved by adding elements from group III of the periodic table, such as boron or gallium, to a pure semiconductor like silicon. The presence of these holes allows for the conduction of electricity, as electrons from neighboring atoms can move into these holes, facilitating current flow.
In P-type semiconductors, the majority charge carriers are holes, while the minority carriers are electrons. This behavior is crucial in the functioning of various electronic devices, including diodes and transistors. When combined with N-type semiconductors, which have an excess of electrons, they form PN junctions that are essential for many applications in electronics.
