Confining potential for electrons (left panel) and holes (right panel) for an electron-hole system (green lines). The system is confined in a cylindrical quantum dot with a radius of 10 nm and a height of 15 nm with <a onClick="popup('http://www.nanoscalereslett.com/content/7/1/508/mathml/M58','MathML',630,470);return false;" target="_blank" href="http://www.nanoscalereslett.com/content/7/1/508/mathml/M58">View MathML</a> and <a onClick="popup('http://www.nanoscalereslett.com/content/7/1/508/mathml/M59','MathML',630,470);return false;" target="_blank" href="http://www.nanoscalereslett.com/content/7/1/508/mathml/M59">View MathML</a>. The electron probability densities along the axial direction are shown for both the ground (black lines) and first-excited (red lines) states, and only the ground hole state is shown. Different configurations (P, F, α0) are considered: 0, 0, 11.3 nm (a, b); 50 kbar, 0, 11.3 nm (c, d); 100 kbar, 0, 11.3 nm (e, f); 0, 20 kV/cm, 11.3 nm (g, h); and 0, 20 kV/cm, 0 (i, j).
