Abstract

We have grown a variety of oxide nanostructures, including nanodots, nanowires, and nanorings. The growth of these structures relies on precise growth mode control and requires a special pulsed laser deposition system which can work at temperatures above 1000C and at high background oxygen pressures. The dynamics of nanostructure growth have been studied in detail. In particular, we have determined the temperatures and deposition rates necessary for growing dot or wire structures on atomically flat surfaces. The nanostructures have been successfully included in fractional-layer superlattices for easier characterization.
