Fermi weight
WebJun 14, 2024 · For occupied energy levels, e − βϵi = e − ϵi / kT ≈ 1; otherwise, e − βϵi = e − ϵi / kT < 1. This means that the Fermi-Dirac distribution simplifies to the Boltzmann distribution whenever 1 ≫ e − α. We can illustrate that this is typically the case by considering the partition function for an ideal gas. WebOct 14, 2024 · The Fermi energy is defined implicitly, by requiring that the total of the band occupancies f is the number of electrons, N: (1) ∑ b = 0 N b f b = N where N b is the number of bands in the calculation. The occupancy is computed from (2) f b = f ( ϵ b − E F σ)
