The relation between particle density and Fermi energy. This displays the relation between particle density and Fermi energy in the quantum well for binding energy B = 1 eV, mass m = m e = 511 keV/ c2, and − B ≤ E F ≤6 eV. The red curve is the contribution from states bound inside the quantum well, the blue curve is the pure three-dimensional density of states in absence of a quantum well, and the black curve is n(E F ) according to Equations (36) and (37).
