Fermi wavelength scale

WebUsing the Fermi wavenumber, we calculate the Fermi wavelength λ F ≡ 2 π / k F. Plugging in numbers (see exercise) shows that the Fermi wavelength is on the order of the atomic spacing for typical free electron densities in metals … The femtometre (American spelling femtometer) symbol fm derived from the Danish and Norwegian word femten 'fifteen', Ancient Greek: μέτρον, romanized: metrοn, lit. 'unit of measurement') is a unit of length in the International System of Units (SI) equal to 10 metres, which means a quadrillionth of one metre. This distance is sometimes called a fermi and was so named in honour of Italian-American physicist Enrico Fermi, as it is a typical length-scale of nuclear physics.
