摘要
We have performed dynamic simulations of the pull off of a Au contact at a temperature of 1 K. The conductance and the tensile force on the contact are calculated throughout the pull off. There are prominent jumps both in the conductance and in the force. The force and conductance jumps generally coincide with each other, and correspond to abrupt atomic rearrangements in the contact. The correlation between the force and conductance jumps and the effective spring constant of the contact during pull off are in agreement with recent experiments.
