The reason for higher electrical conductivity of doped germanium with phosphorous than pure germanium has to be explained. Concept introduction: Semiconductor: A material which can conduct electricity in range between of metal and an insulator is known as semiconductor. Addition of small amount of impurities increases conductivity of semiconductor and the process is known as doping. n-type and p-type are two types of doped semiconductors. n-type semiconductor: n-type doped semiconductor is the one in which many free electrons are present in conduction band. Example: silicon doped with phosphorous.
