摘要：
Electron transport in gold nanowires is studied by transmission electron microscopy (TEM) simultaneously with conductance measurement by using a scanning tunneling tip as an electrode. Conductance evolution while thinning of a gold nanowire shows sequential steps until it breaks after forming a single atomic chain. The step heights coincide the quantum unit, G(0)=2e(2)/h = (12.9k Omega)(-1), except a little deviation due to multiple reflection. Gold nanowires fabricated in the < 110 > orientation can elongate to a several nanometer in length, and show linear current-voltage relation even for the bias voltage of 0.2V. Gold nanowires, thus, behave as a ballistic conductor, and their conductance is quantized to carry current, 1 mu A per single atomic chain at the bias voltage of 13mV.
