Catalystlike role of impurities in speeding layer-by-layer growth

Correlated Istand Nucleation in Layer-by-Layer Growth

Temporal correlations of nucleation events in layer-by-layer growth are studied by simulating a one dimensional model. In order to focus on fluctuations due to the nucle-

Layer-by-Layer Epitaxial Growth of Defect-Engineered Strontium Cobaltites.

Control over structure and composition of (ABO3) perovskite oxides offers exciting opportunities since these materials possess unique, tunable properties. Perovskite oxides with cobalt B-site cations are particularly promising, as the range of the cation's stable oxidation states leads to many possible structural frameworks. Here, we report growth of strontium cobalt oxide thin films by molecul...

Morphology transition and layer-by-layer growth of Rh(111).

We have observed a morphological transition in the nucleation and growth of epitaxial Rh(111). The transition occurs near 600 K and is signaled by a change in the shape of the surface features from fingered to compact. The transition appears to be related to a change in the critical nucleation size. On both sides of the transition, there lies a regime of persistent layer-by-layer growth. The ge...

Pulsed sputtering during homoepitaxial surface growth: layer-by-layer forever

The homoepitaxial growth of initially flat surfaces has so far always led to surfaces which become rougher and rougher as the number of layers increases: even in systems exhibiting ‘‘layer-by-layer’’ growth the registry of the layers is gradually lost. We propose that pulsed glancing-angle sputtering, once per monolayer, can in principle lead to layer-by-layer growth that continues indefinitely...
