Variation of the peak value of the exciton-related nonlinear optical absorption in a cylindrical QD. The variation is a function of the aluminum concentration in the left-hand potential barrier ( <a onClick="popup('http://www.nanoscalereslett.com/content/7/1/508/mathml/M83','MathML',630,470);return false;" target="_blank" href="http://www.nanoscalereslett.com/content/7/1/508/mathml/M83">View MathML</a>).

(a, b) Several values of the hydrostatic pressure with different setups of the applied electric field for α0=3L/4 = 11.3 nm: (a) F = 0 kV/cm and (b) F = 20 kV/cm, have been considered. (c) The results are for two values of the applied electric field with P = 0 and α0 = 0.
