ABSTRACT
High quality quantum dots can be fabricated by using nanoscaie islands grown in coherent Stranski-Krastanow mode as stressors on top of a near-surface quantum well. Size fluctuation of these self-organized islands is an inherent property of the growth process, often leading to broadening of the photoluminescence peaks. In this work the effect of the size fluctuation of the stressor islands on inhomogeneous broadening of photoluminescence measured from a large ensemble of strain-induced quantum dots is studied. The results show that the size fluctuation of the islands is relatively small, and has a negligible effect on the width of the emission peaks from the quantum dots.
