Near-Bulk Conductivity of Gold Nanowires as Nanoscale Interconnects and the Role of Atomically Smooth Interface



original image

Atomically smooth gold nanowires with high aspect ratios are grown using the seeded growth process. This allows control of the diameter of the nanowires to a high degree of precision. Two and four-probe nanoscale transport measurements reveal that the nanowires have low resistivity. Only a small increase in resistivity is observed between diameters of 29 nm and 185 nm suggesting that surface scattering is only a small contribution.
