Morphological evolution of Ge/Si(001) quantum dot rings formed at the rim of wet-etched pits
We demonstrate the formation of Ge quantum dots in ring-like arrangements around predefined {111}-faceted pits in the Si(001) substrate. We report on the complex morphological evolution of the single quantum dots contributing to the rings by means of atomic force microscopy and demonstrate that by c...
