Abstract
Forces contributing to the effective valence Z* in electromigration have been theoretically studied for the following systems: An impurity in the vicinity of, a grain boundary, an impurity in the vicinity of a dislocation, and impurity in a disordered system. The presence of a grain boundary or dislocation was found to change Z* and the residual resistivity by an amount on the order of 10% to 50%. The local transport field in mesoscopic systems was investigated, and the calculations suggest that the scanning tunneling microscope can effectively probe this field. Non-adiabatic recoil effects in the wind force exerted on an impurity were also considered. Electromigration, Effective valence, Mesoscopic systems, Electron transport theory.
