Tīmeklis2024. gada 26. aug. · The Fermi Level is the maximum energy level that an electron may occupy when it is at absolute zero degrees Fahrenheit. Since the electrons are all in the lowest energy state at absolute zero, the Fermi level is located between the valence band and conduction band. Semiconductor materials play a vital role in the field of …
