Ordered InAs QDs using prepatterned substrates by monolithically integrated porous alumina
Pablo Alonso-González, MarÃa S. MartÃn-González, Javier MartÃn-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…
