摘要：

We report on recent experiments on semiconductor quantum rings, fabricated by self-organized Stranski-Krastanov growth. In the first part of this review we focus on the growth mechanisms that lead to formation of annular islands, with emphasis on the influence of diffusion and surface tension. In the second part, we summarize the results of intraband spectroscopy, which show the influence that the ring morphology has on the electronic properties, in particular, when a magnetic flux quantum threads the interior of the islands.
