1947Jrnl. Res. Nat. Bureau of Standards (U.S.) XXXVIII. 137 A new electromigration method for the separation of isotopes is described. 1964M. Gowing Britain & Atomic Energy, 1939–1945 viii. 225 Dr London at Bristol had started work on the electro-migration method which depended on differences in ionic mobility. 1975Physics Bull. Nov. 501/2 Subsequent chapters concerned with metals deal with fast diffusion processes.., hydrogen diffusion.., electromigration..and atom fluxes generated by vacancy winds. 1986Sci. Amer. Oct. 118A/1 The current densities of integrated circuits are so large that they can actually lead to the motion of material from one part of a metal line to another. Once such electromigration begins it is self-perpetuating. |
