Optical Characterization of the Interplay Between Carrier Localization and Carrier Injection in Self-Assembled GaSb/GaAs Quantum Dots

The optical properties of a heterostructure containing GaSb/GaAs quantum dots (QDs) have been systematically investigated via photoluminescence (PL) measurements to gain insights into carrier dynamics. The QD and wetting layer (WL) emissions exhibit a complementary dependence on the excitation inten...
