Low-temperature photoluminescence of short-period GaAs/AlAs superlattices

Experimental data were found to be in qualitative agreement with theoretical calculations of the degree of linear polarization. The effect of the pumping level on the shape of photoluminescence spectra of superlattices with various types of bands was established. The electron-phonon coupling constan...

Description
Summary:Experimental data were found to be in qualitative agreement with theoretical calculations of the degree of linear polarization. The effect of the pumping level on the shape of photoluminescence spectra of superlattices with various types of bands was established. The electron-phonon coupling constants of type-II superlattices were evaluated.
