Ordered InAs QDs using prepatterned substrates by monolithically integrated porous alumina
Pablo Alonso-González, María S. Martín-González, Javier Martín-Sánchez +2
In this work, we explore a method for obtaining site-controlled InAs quantum dots (QDs) on large areas of GaAs (0 0 1) pre-patterned surface. The patterning of the substrate is obt…
New process for high optical quality InAs quantum dots grown on patterned GaAs(001) substrates
Pablo Alonso-Gonzalez, Luisa González, Yolanda González +4
This work presents a selective ultraviolet (UV)-ozone oxidation-chemical etching process that has been used, in combination with laser interference lithography (LIL), for the prepa…
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…
Ordered InAs quantum dots on pre-patterned GaAs (0 0 1) by local oxidation nanolithography
J. Martín-Sánchez, Y. González, L. González +5
Ordered InAs quantum dot (QD) arrays have been obtained on pre-patterned GaAs (0 0 1) substrates by atomic force microscopy (AFM) local oxidation nanolithography. Prior to InAs mol…
Evidence for a Bose-Einstein condensate of excitons
Mathieu Alloing, Mussie Beian, Maciej Lewenstein +6
The demonstration of Bose-Einstein condensation in atomic gases at micro-Kelvin temperatures is a striking landmark while its evidence for semiconductor excitons still is a long-aw…
Observation of macroscopic coherence in self-organized dipolar excitons
M. Alloing, D. Fuster, Y. Gonzalez +2
We report experiments showing that spatially indirect excitons confined in a wide single quantum well can exhibit macroscopic spatial coherence. Extended coherence is spontaneously…
