摘要
The absorption edge spectra and excitonic absorption index integrated over frequency were measured for semiconductor solid solutions AlxGa1-xAs with large concentrations of substituting Al (x = 0.15 and 0.21). For the ground-state exciton the temperature dependence of integral absorption was established to possess features characteristic of exciton-polaritons in a quasi-homogeneous semiconductor with spatial dispersion.
