N2 - A thin quantum well called the wetting layer is created whenever self-assembled quantum dots are fabricated. The wetting layer is highly non-uniform, thereby producing potential fluctuations that influence the physics of the quantum dots. Here, we report several effects that are caused by such fluctuations. In particular, light-induced spectral diffusion on a very long time scale and interdot excitation transfer are observed in a sample of InAlAs quantum dots. We show that the existence of both these phenomena is due to the wetting layer fluctuations.
