Fermi-Dirac Distribution Calculator
Calculate the probability of occupation for fermions at a given energy and temperature.
Cu: 7.0 eV, Au: 5.5 eV, Na: 3.2 eV
2 for spin-1/2 particles (electrons)
Results
Occupation Probability f(E): 1.000000
Average Occupation Number: 2.000000
Regime: Classical tail
Exponent (E - EF)/kT: -19.3387
kT: 0.025855 eV
Fermi Temperature: 63818 K
T/TF (degeneracy parameter): 4.7009e-3
Fermi-Dirac Distribution
f(E) = 1 / (exp((E - EF)/kT) + 1)
For fermions (half-integer spin): electrons, protons, neutrons, quarks
Pauli exclusion: maximum one fermion per quantum state
At E = EF: f(EF) = 0.5 (at any T > 0)
