FIG. 1.

Characterization of a single Pd nanowire between Au electrodes on a wafer. (a) Visualization by scanning electron microscopy. The wire self-assembled from Pd acetate solution between a gap and had a diameter of . Pd acetate solution was diluted 8-fold from saturation, the source was at 300 kHz, and dc offset 0.8 V. (b) atomic force microscopy image of a portion of the nanowire shown (a). Vertical scale, 90 nm. Irregularity in wire diameter will increase electrical resistance. (c) Electron-dispersive x-ray analysis. Evidently, the nanowire is made mostly if not exclusively of Pd. Inset: electrical characterization of the nanowire in (a). The resistance was .

Ability of various metal salts or complexes to form nanowires under an applied signal of 300 kHz and 0.8 V dc. (a) . (b) . (c) . (d) . (e) . (f) . Each solution was saturated, buffered with 10 mM HEPES at , and prepared at room temperature except (b), for which the concentration was . These data could help to rule out some possible mechanisms of formation of the nanowire shown in Fig. 1(a).
