The Fermi wavevector is the radius of the occupied <sphere> in <wavevector> coordinates for an isotropic <Fermi gas>. In the uniform two-component <Electron> model, $k_F=(3\pi^2n)^{1/3}$ and $E_F=\hbar^2k_F^2/(2m_e)$ for <nonrelativistic particles>. Its units are inverse <length>, whereas the <Fermi momentum> has units of <momentum>.
