Figure 53. Total optical absorption spectra (in units of W0), as a function of the hw — sg, for valence to donor transitions in infinite GaAs-(Ga,Al)As quantum dots of different radii. r0 = 3000 A (a) and r0 = 500 A (b) for a quantum dot with a homogeneous distribution of impurities, where there is no interaction between them.
