The density of states in the quantum well. This displays the density of states in the quantum well location z = z0 for binding energy B = 1 eV, mass m = me = 511 keV/c2, and energies −B E≤ 3 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 the density of states according to equation (34).
