FIG. 1.

(a) DNA base sequences of synthetic dsDNA molecules. The arrows indicate simplified strands running from to . The complementary sticky end of is . (b) An atomic-resolution cartoon of a unit dsDNA molecule which consists of 50 base pairs with 46% CG content.

FIG. 2.

(a) AFM image of -DNA in air. (b) AFM image of synthetic dsDNA in liquid phase. (Inset) In a high resolution AFM image with a periodic bump pattern on the dsDNA. (c) and (d) are height measurements of single -DNA in air and synthetic dsDNA molecules under buffer. (e) and (f) are SEM images of - and synthetic-dsDNA after two-step silver metallization process.

FIG. 3.

(a) Linear two-terminal characteristics of silver nanowires. (Inset) Initial high resistance can be reduced by applying bias voltage. The white arrow indicates voltage sweep direction. After the first few sweeps of bias voltages, current dramatically changes at a certain critical voltage (here, ). (b) The curves of a silver nanowire measured at two different temperatures, 300 and . (Inset) SEM image of an actual device with scale bar, . Cr–Au double layer electrodes, with of Cr followed by of Au, were patterned by electron beam lithography onto the nanowires on the silicon substrate.

FIG. 4.

Nonlinear two-terminal characteristics of silver nanowires. About 15% of total number of measured nanowires are non-Ohmic and may have slightly asymmetrical with respect to zero bias. Among them, three data sets, two from indicated L1 and L2 and the other S from synthetic-dsDNA templated wires, are shown.
