“…4 This anomaly has historically been attributed to the onset of some additional diffusion mechanism contributing at high temperature. However, all such ad hoc assumptions have been ruled out, 10 and it is now believed that the vacancy mechanism alone is responsible for self-diffusion in bcc metals, as it is in fcc metals. The selfdiffusion rate D then depends on the vacancy concentration c v and the vacancy migration rate ⌫ v as…”

“…A general theory for electromigration has been published before. [28] The force causing atom displacements is expressed as the sum of a direct electrostatic force and an electron-mediated "wind force". [28] The current densities required for Cu electromigration in bamboo-like CNTs were measured to be 3.07 × 10 6 A cm -2 .…”

[28] The current densities required for Cu electromigration in bamboo-like CNTs were measured to be 3.07 × 10 6 A cm -2 . [7] Regretfully, the maximum passing currents through the tubes during the present longitudinal or transverse Cu flows were not precisely measured in our experiments.…”
