Temperature dependence of the energy spectrum of metamorphic InSb/In(Ga,Al)As/GaAs heterostructures studied using FTIR photoreflectance spectroscopy

The paper presents the results of studies of InSb/In(Ga,Al)As/GaAs heterostructures using the photoreflectance method. Based on the results of the work, the temperature dependences of the observed transition energies were obtained, the values of the miniband width and spin-orbit splitting were determined.
