Journal ArticleDOI
In(Ga)As self-assembled quantum ring formation by molecular beam epitaxy
Daniel Granados,Jorge M. Garcia +1 more
TL;DR: In this paper, the effect of growth conditions on the morphological properties of InAs/GaAs(001) quantum dots covered by a thin (<3 nm) GaAs cap has been studied by atomic force microscopy.
Journal ArticleDOI
Manipulating exciton fine structure in quantum dots with a lateral electric field
Brian D. Gerardot,Stefan Seidl,Paul A. Dalgarno,Richard J. Warburton,Daniel Granados,Jorge M. Garcia,K. Kowalik,Olivier Krebs,K. Karrai,Antonio Badolato,Pierre M. Petroff +10 more
TL;DR: In this article, the fine structure of the neutral exciton in a single self-assembled InGaAs quantum dot is investigated under the effect of a lateral electric field, showing that the electric field strongly affects the exciton fine-structure splitting due to active manipulation of the single particle wave functions.
Journal ArticleDOI
Oscillatory persistent currents in self-assembled quantum rings.
Najm Niek Kleemans,I.M.A. Bominaar-Silkens,Vladimir M. Fomin,Vladimir M. Fomin,V. N. Gladilin,Daniel Granados,Alfonso G. Taboada,Jorge M. Garcia,Peter Offermans,Uli Zeitler,Pcm Christianen,Jan C. Maan,J. T. Devreese,J. T. Devreese,PM Paul Koenraad +14 more
TL;DR: The first Aharonov-Bohm oscillation is measured at a field of 14 T, in perfect agreement with the model based on the structural properties determined by cross-sectional scanning tunneling microscopy measurements.
Journal ArticleDOI
Atomic-scale structure of self-assembled In(Ga)As quantum rings in GaAs
Peter Offermans,PM Paul Koenraad,JH Joachim Wolter,Daniel Granados,Jorge M. Garcia,Vladimir M. Fomin,V. N. Gladilin,J. T. Devreese +7 more
TL;DR: In this article, an atomic-scale analysis of the indium distribution of self-assembled In(Ga)As quantum rings (QRs) is presented, which are formed from InAs quantum dots by capping with a thin layer of GaAs and subsequent annealing.
Journal ArticleDOI
Room temperature emission at 1.6μm from InGaAs quantum dots capped with GaAsSb
José María Ripalda,Daniel Granados,Yolanda González,Ana M. Sanchez,Sergio I. Molina,Jorge M. Garcia +5 more
TL;DR: In this paper, room temperature photoluminescence at 1.6μm was demonstrated from InGaAs quantum dots capped with an 8nm GaAsSb quantum well.
