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 ...
