Self-Organization of Heteroepitaxial CeO2 Nanodots Grown from Chemical Solutions

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‐co...

Zusammenfassung: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.
