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…
