FAQ

What is the Fermi Energy?
Fermi Energy a quantum mechanical concept that refers to the energy difference between the highest and lowest occupied states of a system of non-interacting fermions at absolute zero temperature. Fermi Energy is usually measured using the Joule for Energy. Note that the value of Fermi Energy is always negative.
Can the Fermi Energy be negative?
Yes, the Fermi Energy, measured in Energy can be negative.
What unit is used to measure Fermi Energy?
Fermi Energy is usually measured using the Joule[J] for Energy. Kilojoule[J], Gigajoule[J], Megajoule[J] are the few other units in which Fermi Energy can be measured.
