Binding energy of 1s-like heavy-hole exciton state as a function of left-hand- potential-barrier aluminum concentration (). The results are for the ground exciton state (ne = 1 and nh = 1) with , L = 15 nm, and R = 10 nm. (a, b) Several values of the hydrostatic pressure with different setups of the applied electric field for α0(P) = 3L(P)/4: (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.
