Intrinsic conduction refers to the ability of certain materials to conduct electricity without the need for any external influence or stimulation. This type of conduction occurs naturally within the material itself, due to the presence of free electrons or ions that can move freely and carry electrical charge.
Extrinsic conduction, on the other hand, refers to the ability of a material to conduct electricity only when certain external factors, such as temperature, light, or pressure, are applied. In this case, the material does not conduct electricity on its own, but can be made to do so by manipulating its environment. Examples of extrinsic conductors include semiconductors, which can be made to conduct electricity by doping them with impurities.

Intrinsic conduction occurs in pure or intrinsic semiconductors without the addition of any impurities. In intrinsic semiconductors, the number of holes is equal to the number of electrons, and the Fermi level is located exactly in the middle of the band gap.
Extrinsic conduction occurs in semiconductors that have been doped with impurities. When a semiconductor is doped with a donor impurity, such as phosphorus, the number of electrons in the semiconductor increases, and the Fermi level moves closer to the conduction band. When a semiconductor is doped with an acceptor impurity, such as boron, the number of holes in the semiconductor increases, and the Fermi level moves closer to the valence band.
The main difference between intrinsic and extrinsic conduction is the source of the charge carriers. In intrinsic conduction, the charge carriers are generated by the thermal excitation of electrons from the valence band to the conduction band. In extrinsic conduction, the charge carriers are generated by the ionization of dopant atoms.
Intrinsic conduction is typically undesirable in electronic devices because it results in a high concentration of both electrons and holes, which can lead to increased leakage currents and reduced device efficiency. Extrinsic conduction is typically used to control the electrical properties of semiconductors in electronic devices.
