摘要：

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 2e(2)/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.
