The force of electromigration

Abstract

Considerations of momentum conservation, applied to the simple semi classical model studied in a previous paper (see ibid., vol.6, p.2811 (1973)) lead to a relation between the force on the ion and the resistance change of the metal caused by the ion. The result includes the direct force of the field on the ion, any screening correction, the electron wind, and the force due to the carrier density modulation.
