Solution
Doping is the process of adding small amounts of impurities to a material. This process has a drastic effect on the properties of the material.
When some materials are doped, they form an excess of electrons, resulting in the formation of an n-type semiconductor. On the other hand, when other materials are doped, they form an excess of holes, leading to the formation of a p-type semiconductor.
Both n-type and p-type semiconductors have much greater conductivity than pure semiconductors. This increased conductivity is known as extrinsic conduction.
