    <dcterms:abstract xml:lang="eng">We have studied controlled electromigration (EM) in free-standing copper wires. Besides electrical characterization by voltage–current measurements, structural analyses have been performed by means of scanning electron microscopy and cross-sectional microprobe measurements. We have found that oxidation during the EM in air stabilizes the free-standing wire against uncontrolled blowing, making it possible to thin the conductive part of the wire down to a conductance of a few conductance quanta G&lt;sub&gt;0&lt;/sub&gt;=2e&lt;sup&gt;2&lt;/sup&gt;/h. The decisive influence of oxidation by air on the EM process was confirmed by control experiments performed under ultra-high vacuum conditions. In line with these findings, free-standing Au wires were difficult to thin down reproducibly to a conductance of a few G&lt;sub&gt;0&lt;/sub&gt;. Estimates of the local temperature in the free-standing wire are obtained from finite element method calculations.</dcterms:abstract>
