Answer» Adding of impurities to SEMICONDUCTOR is doping. Materials which are used in semiconductor devices are generally of silicon , GERMANIUM etc . The impurities belong to either boron family members like gallium , indium to make p- type SEMICONDUCTORS and to make n-type semiconductors we USE nitrogen famiily members to make n-type semiconductors like phosphorus , arsenic etc Doping is done because ADDITION of small qty of them causes dramatic changes in the electrical properties.
