Self-organized rows of CeO2 nanodots (see image) have been achieved through centering of islands within the terraces of vicinal perovskite substrates. The extraordinary effectiveness for lateral confinement, with islands' heights ∼ 20 times larger than the lattice steps, results from the non-coherent vertical interfaces at the substrate steps between dissimilar crystallographic structures.
