Compositional analysis of InAs-GaAs-GaSb heterostructures by Low-Loss Electron Energy Loss Spectroscopy
(Institute of Physics Publishing, 2013)
As an alternative to Core-Loss Electron Energy Loss Spectroscopy, Low-Loss EELS is suitable for compositional analysis of complex heterostructures, such as the InAs-GaAsGaSb system, since in this energy range the edges ...

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 ...
