The transition dipole matrix element between the ground and first-excited exciton states in a cylindrical QD. The asymmetrical axial potential configuration is a function of the aluminum concentration in the left-hand potential barrier ( ). The results are for , L = 15 nm, and R = 10 nm. (a, b) Several values of the hydrostatic pressure with different setups of the applied electric field for values of the intense laser parameter α₀(P) = 3L(P)/4 = 11.3 nm: (a) F = 0 kV/cm and (b) F = 20 kV/cm, have been considered. (c) The results appear for two values of the applied electric field with P = 0 and α₀ = 0.
