pub fn free_electron_fermi_energy_ev(n_per_m3: f64) -> f64Expand description
Free-electron Fermi energy, eV, for n conduction electrons per m³:
Verduin Eq. 3.133 (p. 95), n = (2 sqrt 2 / 3π²) (m_e E_F / ħ²)^(3/2),
solved for E_F, which gives E_F = (ħ² / 2 m_e) (3π² n)^(2/3). CODATA
constants from crate::constants.
