Abstract:
Lines conditioned by the transitions hh,lh1-e1(1s,2s,3s), hh2,lh2-e2(1s,2s,3s), hh1,lh1-e2(1s) and hh3,lh3-e3(1s) had been revealed in reflection spectra of In0.3 Ga0.7As / GaAs nanostructures. The shapes of the reflection and transparency lines had been calculated, using a single oscillator model of dispersion correlations and the Kramers-Kronig integrals. The excitons’ parameters in quantum wells (QW) and quantum dots (QD) had been determined.
