DOI: 10.1088/1612-202x/aba0bf
Abstract: We show that the density of states and gain spectra of InGaAs/GaAs quantum well-dot (QWD) hybrid nanostructures qualitatively differ from that of quantum wells (QWs) and quantum dots. In QWDs, the density of states does… read more here.

DOI: 10.1134/s1063785020010204
Abstract: Abstract Low-temperature circularly polarized electroluminescence in InGaAs/GaAs/δ-〈Mn〉 heterostructures has been studied. It is established that the degree of circular polarization weakly depends on spatial separation of the active region and magnetic layer and is retained… read more here.
