WitrynaThe impurities add “donor atoms” to the base material, encouraging conductivity. The amount of impurities added to semiconductor materials is minuscule—as little as one donor atom per ten million semiconductor atoms—but sufficient enough to allow electrical conductivity. Two categories of impurities are used, N-type and P-type: N … WitrynaExtrinsic (impurity) semiconductor: Inorder to increase the conductivity, it is often to introduce the foreign atoms (impurity or dopant) into the intrinsic semiconductor; the resulted semiconductor with impurity atoms is known as extrinsic semiconductor. These dopants are added to the semiconductor in small amount (about 1 part in 10 8 ). WitrynaImpurities are added into a semiconductor to actually increase the electric conductivity.
