The substructure and luminescence of low-temperature AlGaAs/GaAs(100) heterostructures
The substructure and luminescence of low-temperature epitaxial AlGaAs alloys are studied by Raman spectroscopy and photoluminescence spectroscopy. It is shown that the experimental data obtained in the study a...

The effects of the porous buffer layer and do** with dysprosium on internal stresses in the GaInP:Dy/por-GaAs/GaAs(100) heterostructures
In structures with a porous buffer layer, residual internal stresses caused by a mismatch between the crystal-lattice parameters of the epitaxial GaInP alloy and the GaAs substrate are redistributed to the por...
