WebFermi circle • All quantum states inside the Fermi circle are filled (i.e. occupied by electrons) • All quantum states outside the Fermi circle are empty Fermi Momentum: The largest momentum of the electrons is: This is called the Fermi momentum Fermi momentum can be found if one knows the electron density: kF 2 1 kF 2 n Fermi Energy: WebThe energy at the surface of this sphere is the Fermi energy EF. The magnitude of the Fermi wave vector kF and the Fermi energy are related by the equation: The Fermi energy and the Fermi momentum are determined by the number of valence electrons in the system N.
