(Color online) SEM images of gold nanowires of 100 nm in diameter observed with (a) low magnification and (b) high magnification.
(a) TEM image of a 53 nm gold nanowire with obvious uniform contour and (b) SAED pattern of the gold nanowire shown in (a).
(Color online) The schematic description of two different modes for investigating the optical properties. The gold nanowires embodied in the etched ion-track template are highly parallel to each other. α is the angle between propagation direction of inject light and long axes of nanowires, (a) α = 0° and (b) 0° < α < 90°; the X and Y axes are along the short axes of the gold nanowires, and Z-axis is parallel to the long axis.
(Color online) Extinction spectra of gold nanowire arrays with the diameters from 30 to 130 nm. The area density of the gold nanowires measured here is wires/cm2.
(Color online) Extinction spectra of 80 nm gold nanowires with different incidence angles α. The area density of gold nanowire measured is wires/cm2.
SEM images of a single gold nanowire for measuring the failure current density. (a) Before performing the measurement; (b) disrupted gold nanowire by a high current density.
(Color online) (a) The record I-V curve of single gold nanowire for measuring maximum current density, the dotted line is used to guide the eye; (b) failure current density of single gold nanowires as a function of diameter.
