单原子宽度的金线是通过拉伸金纳米接触，使用高分辨率透射电子显微镜内的piezomanipulation。的电线的结构进行了观察，同时电导测量原位。导线的电导取决于长度;当长度从1个原子增加到7个原子时，电导从1G 0下降到0.1G0（G 0 = 2 e 2/h，其中e是电子的电荷，h是普朗克常数）。结果表明，弹道传导击穿的导线。
Single-atom-width gold wires were produced by stretching gold nanocontacts using piezomanipulation inside a high-resolution transmission electron microscope. The structure of the wires was observed in situ with simultaneous conductance measurements. The conductance of the wires depended on the length; the conductance decreased from 1G0 to 0.1G0 (G0 = 2e 2/h, where e is the charge of an electron and h is Planck's constant) as the length increased from 1 atom to 7 atoms. The results show that ballistic conduction breaks down in the wires.
