摘要：
We have grown similar to1-420 nm thick epitaxial Co wedges on Ru(0001) with molecular-beam epitaxy at 350 degreesC and characterized them with atomic force microscopy. A metal-on-metal growth mode was observed where three-dimensional islands (dots) or a flat film network with holes (antidots) in truncated pyramidal shapes exist below or above similar to 20 nm, respectively. The top of the islands and the rim of the holes are flat with a roughness of similar to0.3 nm, and the lateral sizes of these dots/antidots, similar to 10(2) nm, tend to be uniform. We suggest that this self-assembled growth be mainly driven by strain. (C) 2001 American Institute of Physics.
