Web6 jul. 2016 · The two categories of impurities are n-type and p-type. N-Type Semiconductor To increase the number of conduction-band electrons in intrinsic silicon, pentavalent impurity atoms are added. These are atoms … Web21 mrt. 2024 · There are further two types of extrinsic semiconductors. N-Type Extrinsic Semiconductors; P-Type Extrinsic Semiconductors; Intrinsic types of Semiconductors. Intrinsic type semiconductor is one which is made from a semiconductor material in an extremely pure form; it does not have amalgamation of any other material. WebExtrinsic Semiconductors (semiconductors in which impurities are added): When impurity is added in pure semiconductor, it becomes Extrinsic semiconductor. There are two types of Extrinsic semiconductors: P-type and N-type. P-type semiconductor: It contains large number of holes. Since holes have positive charge, the material becomes P-type. potter\u0027s box
