electromigration1947
1947 Jrnl. Res. Nat. Bureau of Standards (U.S.) 38 137 A new electromigration method for the separation of isotopes is described.
1964 M. Gowing Brit. & Atomic Energy 1939–45 viii. 225 Dr London at Bristol had started work on the electro-migration method which depended on differences in ionic mobility.
2001 R. W. Cahn Coming of Materials Sci. vii. 263 Many materials scientists have worked on the problem of electromigration in the thin metallic conductors built into integrated circuits, a process which eventually leads to short circuits and circuit breakdown.
2007 Internat. Jrnl. Refrigeration 20 292/1 The electromigration of these ions will drag the bulk fluid through viscous interaction.
