摘要：
We studied experimentally the influence of the size of GaN quantum dots on the exciton photoluminescence at 10 K under high optical excitation for which the spatial confinement was found to be a critical parameter for optical nonlinearities such as band-gap renormalization (BGR) and state-filling effects. As the dot size decreases, the BCR characteristic of bulk like dots becomes dominated by the state-filling nonlinearity. in addition, three-dimensional confinement is demonstrated by a comparison with a quantum well.
