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.
