Impurity atoms in semiconductors
Witryna3 lis 2024 · An intrinsic semiconductor is a single crystal made from a pure semiconductor through a certain process. Intrinsic semiconductors are semiconductors with complete crystal lattices without any impurities. Its conductivity is not affected by any impurities or lattice defects, and is only determined by the nature … WitrynaIn the physics of semiconductors, an acceptor is a dopant atom (impurity) that, when added to a semiconductor, can form a p-type semiconductor. The process of adding controlled impurities to a semiconductor is known as semiconductor doping, and this process changes an intrinsic semiconductor to an extrinsic semiconductor.
