Effects of GaAs(Sb) cladding layers on InAs/AlAsSb quantum dots

(author unknown)



Meng Sun, Paul J. Simmonds, and Ramesh Babu Laghumavarapu et al.

The structural and optical properties of InAs self-assembled quantum dots buried in AlAs0.56Sb0.44 barriers can be controlled using GaAs1−xSbx cladding layers. These cladding layers allow us to manage the amount of Sb immediately underneath and above the InAs quantum dots. The optimal cladding sch ... [Appl. Phys.
