Structural and optical changes induced by incorporation of antimony into InAs/GaAs(001) quantum dots
A. G. Taboada, A. M. Sánchez, A. M. Beltrán +12
We present experimental evidence of Sb incorporation inside InAs/GaA(001) quantum dots exposed to an antimony flux immediately before capping with GaAs. The Sb composition profile…
Spin dependent analysis of homogeneous and inhomogeneous exciton decoherence in magnetic fields
V. Laurindo, E. D. Guarin Castro, G. M. Jacobsen +9
This paper discusses the combined effects of optical excitation power, interface roughness, lattice temperature, and applied magnetic fields on the spin-coherence of excitonic stat…
Magnetically controlled exciton transfer in hybrid quantum dot-quantum well nanostructures
V. Laurindo, Yu. I. Mazur, E. R. Cardozo de Oliveira +8
A magnetophotoluminescence study of the carrier transfer with hybrid InAs/GaAs quantum dot(QD)-InGaAs quantum well (QW) structures is carried out where we observe an unsual depende…
Strain-balanced type-II superlattices for efficient multi-junction solar cells
A. Gonzalo, A. D. Utrilla, D. F. Reyes +9
We propose type-II GaAsSb/GaAsN superlattices (SLs) lattice-matched to GaAs as a novel material for the 1 eV sub-cells present in highly efficient GaAs/Ge-based multi-junction sola…
Probing quantum confinement within single core-multishell nanowires
Gema Martínez-Criado, Alejandro Homs, Benito Alén +6
Theoretically core-multishell nanowires under a cross-section of hexagonal geometry should exhibit peculiar confinement effects. Using a hard X-ray nanobeam, here we show experimen…
Charge control in laterally coupled double quantum dots
G. Muñoz-Matutano, M. Royo, J. I. Climente +9
We investigate the electronic and optical properties of InAs double quantum dots grown on GaAs (001) and laterally aligned along the [110] crystal direction. The emission spectrum…
