Witryna28 mar 2024 · A N-type semiconductor is defined as a type of extrinsic semiconductor doped with a pentavalent impurity element which has five electrons in its valence shell. The pentavalent impurity or dopant elements are added in the N-type semiconductor to increase the number of electrons for conduction. Doping in N-type Semiconductor WitrynaThe donor impurity atom consists of a total of 5 electrons in its valence shell. While acceptor impurity atom consists of 3 electrons in its valence shell. An element like phosphorus, antimony, bismuth, arsenic, etc is donor impurities. While boron, gallium, aluminum, etc are the acceptor impurity atoms.
