We show that either a blueshift or a redshift of the fundamental transition energy can be observed in vertical arrays of InAs/GaAs quantum dots, depending on the spacer thicknesses, and explained by including strain, indium segregation, and Coulomb effects.

Abstract
We show that either a blueshift or a redshift of the fundamental transition energy can be observed in vertical arrays of InAs/GaAs quantum dots, depending on the spacer thicknesses, and explained by including strain, indium segregation, and Coulomb effects.File in questo prodotto:
