From Favorable Atomic Configurations to Supershell Structures: A New Interpretation of Conductance Histograms
From Favorable Atomic Configurations to Supershell Structures: A New Interpretation of Conductance Histograms
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 …
