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.
