Theoretical modelling of quaternary GaInAsSb/GaAs self-assembled quantum dots
(Institute of Physics Publishing, 2010)
InAs/GaAs quantum dots exposed to Sb after growth exhibit spectral changes. We study in the present paper an idealized nanostructure consisting of a homogeneous distribution of the quaternary GaInAsSb surrounded by a barrier ...

Structural and optical changes induced by incorporation of antimony into InAs/GaAs(001) quantum dots
(American Physical Society, 2010)
We present experimental evidence of Sb incorporation inside InAs/GaAs 001 quantum dots exposed to an antimony flux immediately before capping with GaAs. The Sb composition profile inside the nanostructures as measured by ...
