TY - JOUR ID - 1556922 AU - Klenovský, Petr - Schliwa, Andrei - Bimberg, Dieter PY - 2019 TI - Electronic states of (InGa)(AsSb)/GaAs/GaP quantum dots JF - Physical Review B VL - 100 IS - 11 SP - 115424 EP - 115424 PB - American Physical Society SN - 24699950 KW - Quantum Dots;Electronic structure;Multiparticle states UR - https://journals.aps.org/prb/abstract/10.1103/PhysRevB.100.115424 L2 - https://journals.aps.org/prb/abstract/10.1103/PhysRevB.100.115424 N2 - Detailed theoretical studies of the electronic structure of (InGa)(AsSb)/GaAs/GaP quantum dots are presented. This system is unique since it exhibits concurrently direct and indirect transitions both in real and momentum space and is attractive for applications in quantum information technology, showing advantages as compared to the widely studied (In,Ga)As/GaAs dots. We proceed from the inspection of the confinement potentials for k!=0 and k=0 conduction and k=0 valence bands, through the formulation of k.p calculations for k-indirect transitions, up to the excitonic structure of Gamma transitions. Throughout this process we compare the results obtained for dots on both GaP and GaAs substrates, enabling us to make a direct comparison to the (In,Ga)As/GaAs quantum dot system. We also discuss the realization of quantum gates. ER -
