Conductance-elongation curves of gold atomic wires are measured using a scanning tunneling microscope break junction technique at room temperature. Landauer's conductance plateaus are individually identified and statistically analyzed. Both the probabilities to observe and the lengths of the two last plateaus (at conductance values close to 2e(2)/h and 4e(2)/h) are studied. All results converge to show that the occurrences of these two conductance plateaus on a conductance-elongation curve are statistically independent events.
在室温下，使用扫描隧道显微镜断接技术测量金原子线的电导-伸长曲线。分别识别并统计分析兰道尔电导平台。研究了观察到最后两个平台（电导值接近2e(2)/h和4e(2)/h）的概率及其长度。所有结果都表明，在电导-伸长曲线上出现这两个电导平台是统计独立事件。
