Abstract :
Summary form only given. We report picosecond and subpicosecond carrier capture times. The measurements were performed on as-grown and intermixed In/sub 0.5/Ga/sub 0.5/As-GaAs quantum dots by time-resolved photoluminescence (PL). The studied quantum dots were grown by metalorganic chemical vapor deposition. Intermixing was performed by postgrowth thermal annealing.
