Phys. Rev. Lett. 86, 5574–5577 (2001)From Favorable Atomic Configurations to Supershell Structures: A New Interpretation of Conductance HistogramsReceived 14 August 2000; published in the issue dated 11 June 2001 Simulated minimum cross-section histograms of breaking Al nanocontacts are produced using molecular dynamics. The results allow a new interpretation of the controverted conductance histogram peaks based on preferential geometrical arrangements of nanocontact necks. As temperature increases, lower conductance peaks decrease in favor of broader and higher conductance structures. This reveals the existence of shell and supershell structures favored by the increased mobility of Al atoms. © 2001 The American Physical Society URL:
