## What are extrinsic semiconductors?

Extrinsic semiconductors are just intrinsic semiconductors that have been doped with impurity atoms (one dimensional substitutional defects in this case). Doping is the process where semiconductors increase their electrical conductivity by introducing atoms of different elements into their lattice.

## What is n-type extrinsic semiconductor?

An n-type semiconductor is created when pure semiconductors, like Si and Ge, are doped with pentavalent elements. when a semiconductor is doped with a pentavalent atom, electrons are the majority charge carriers. On the other hand, the holes are the minority charge carriers. Therefore, such extrinsic semiconductors are called n-type semiconductors. In an n-type semiconductor, Number of free electrons >> Number of holes
