Evidence of shell structures in Au nanowires at room temperature

Abstract:

Statistical conductance properties of gold elongating nanowires at room temperature are studied experimentally. The measured conductance histogram, built with thousands of consecutive nanocontact breakage experiments, exhibits a rich structure of low-intensity peaks at high-conductance quanta values. Their position as a function of a peak index number suggests two markedly different regimes for electronic and atomic shell structures in these nanowires, as observed previously for alkali metal nanowires.
