Abstract :
Self-assembled GaSb quantum dots (QDs) with a photoluminescence wavelength longer than View the MathML source were successfully grown by suppressing the replacement of As and Sb on the surface of the GaSb QDs. This result means that GaSb can thus join InAs or GaInAs as a suitable material for QD lasers for optical communications.
