我们在实验和数值模拟上研究了室温下Al纳米接触的统计电导特性。来自数百个连续实验的测量的电导直方图（CH）表现出接近以2 e2/h为单位的整数值的峰值。最小截面直方图从分子动力学计算得到的结果进行了比较。这些原子的模拟和实验之间的协议提供的证据表明，CH是有利的原子配置的签名。
We study experimentally and numerically the statistical conductance properties of Al breaking nanocontacts at room temperature. The measured conductance histogram (CH) from hundreds of consecutive experiments exhibits peaks close to integer values in units of 2e2/h. The results are compared with minimum-cross-section histograms obtained from molecular dynamics calculations. The agreement between these atomistic simulations and experiments provides evidence that the CH is a signature of favourable atomic configurations.
