The density of states (34) in the quantum well location z = z0 for higher energies 0 ≤ E ≤ 100 eV. The binding energy, mass and color coding are the same as in Figure 4. The full density of states (34) approximates the three-dimensional <a onClick="popup('http://www.nanoscalereslett.com/content/7/1/581/mathml/M85','MathML',630,470);return false;" target="_blank" href="http://www.nanoscalereslett.com/content/7/1/581/mathml/M85">View MathML</a>behavior for energies E B, but there remains a finite offset compared to ϱd = 3 due to the presence of the quantum well.
