Diffusion and Defect Monographs No2

This monograph is devoted to the analysis and investigation of the electrodiffusion phenomenon. The application of an electric field to a metal, alloy, or other material may result in the transport of matter as well as the flow of electrons. This phenomenon, variously described as electrotransport, electromigration, or electrodiffusion, is most commonly manifested in the separation of the components of an alloy which results from their different induced rates or directions of migration. An applied field may similarly produce In pure elements a directed displacement of vacancies or interstitials (self-transport) or different isotopes (the Haeffner effect).
