Incorporation of Sb in InAs/GaAs quantum dots
(American Institute of Physics, 2007)
The formation of a quaternary InGaAsSb alloy is shown to occur in the core of epitaxial GaSb capped InAs/GaAs quantum dots emitting at 1.3 m. The existence of the four constituent elements is demonstrated by using spatially ...

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 ...

Coalescence aspects of III-nitride epitaxy
(American Institute of Physics, 2007-03)
In this work, coalescence aspects of wurtzite-III-nitride epitaxy are addressed. The coalescence phenomena have been studied in thin epilayers by means of electron and atomic force microscopies, and electron and x-ray ...
