An N-Type Semiconductor is a type of material that has been doped with impurities to increase the number of free electrons. This process involves adding elements, such as phosphorus or arsenic, which have more valence electrons than the semiconductor material, typically silicon. The extra electrons contribute to electrical conductivity, making N-Type semiconductors essential in electronic devices. In N-Type semiconductors, the majority charge carriers are negatively charged electrons, while the minority carriers are holes. This characteristic allows N-Type materials to work effectively in conjunction with P-Type semiconductors, creating PN junctions that are fundamental in devices like diodes and transistors.
