By comparison, extrinsic semiconductors are composite materials created by treating or infusing intrinsic semiconductors with other elements from the periodic table (more on this below).

Semiconductors are normally classified into intrinsic semiconductors and extrinsic semiconductors depending on its ‘doping status’. In other words, intrinsic semiconductors are ‘pure ...

Semiconductors are divided into intrinsic semiconductors and extrinsic semiconductors. Chemically pure semiconductors with no impurities, like the examples above, are called intrinsic semiconductors.
