What is Fermi level in energy band diagram?

"Fermi level" is the term used to describe the top of the collection of electron energy levels at absolute zero temperature. This concept comes from Fermi-Dirac statistics. Electrons are fermions and by the Pauli exclusion principle cannot exist in identical energy states.

Hereof, what is the intrinsic concentration?

- ni is the intrinsic carrier concentration, i.e., the number of electrons in the conduction band. (and also the number of holes in the valence band) per unit volume in a semiconductor. that is completely free of impurities and defects.

What is intrinsic and extrinsic material?

Semiconductor doping is the process that changes an intrinsic semiconductor to an extrinsic semiconductor. Acceptor impurity atoms have fewer valence electrons than the atoms they replace in the intrinsic semiconductor lattice. They "accept" electrons from the semiconductor's valence band.

What is the quasi Fermi level?

A quasi Fermi level (also called imref, which is "fermi" spelled backwards) is a term used in quantum mechanics and especially in solid state physics for the Fermi level (chemical potential of electrons) that describes the population of electrons separately in the conduction band and valence band, when their
