The maximum energy upto which the electron occupies in a semiconductor at an absolute zero temperature is called as ___________

The maximum energy up to which the electron occupies in a semiconductor at absolute zero temperature is called the Fermi level.

At absolute zero, all the electrons fill the available energy states up to a certain maximum energy level, which defines the highest occupied state. In intrinsic (pure) semiconductors, this Fermi level is located near the middle of the energy band gap between the conduction band and the valence band. The Fermi level plays a crucial role in determining the electrical properties of semiconductors, as it influences the distribution of electrons and holes within the material. Understanding the position of the Fermi level is essential for predicting how the semiconductor will behave under different temperatures and doping conditions.
