The presence of large objects in MOVPE grown self-assembled quantum dot samples was studied. Creation of large objects and high indium concentration inside was explained as a combined process of accumulation of In atoms on the surface and their following long-range surface migration.

We have found that the abruptness and symmetry on monoatomic scale is achievable with MOVPE technique as well. We are able to find only the periodicity in these structures while atomic resolution pictures give reliable thickness values.
