Question: Describe in detail extrinsic semiconductor and doping?

An extrinsic semiconductor is a type of semiconductor that has been doped with impurity atoms to change its electrical properties. Doping is the process of introducing atoms of a different element than the intrinsic semiconductor into its crystal lattice. There are two types of dopants: pentavalent and trivalent. Pentavalent dopants have five valence electrons and can donate one electron to the semiconductor, creating an n-type semiconductor. Trivalent dopants have three valence electrons and can accept one electron from the semiconductor, creating a p-type semiconductor. The doping process increases the conductivity of the semiconductor by providing more charge carriers, either electrons or holes, that can move freely in the material.
