interstitialcy Physics.|ɪntəˈstɪʃəlsɪ|
[f. interstitial a. + -cy, after vacancy.]
A kind of imperfection in a crystal lattice, characterized by an interstitial atom able to displace an atom from an adjacent lattice position so that it becomes the interstitial in its turn, able to displace another atom.
1950F. Seitz in Acta Crystallogr. III. 361/1 The lattice imperfection which is the inverse counterpart of a lattice vacancy is an interstitial atom which moves by jumping into a normal lattice site and forces the atom that is there into a neighboring interstitial site... We shall term it an interstitialcy. Ibid. 361/2 The interstitial atom associated with a passing interstitialcy at any point in its migration may be either an A atom or a B atom. 1956Physical Rev. CI. 1210/2 The effects discussed here may be useful in distinguishing experimentally between interstitialcy and vacancy migration in other crystals. 1967F. C. Brown Physics of Solids x. 315 In the silver halides the interstitial ion moves by an interstitialcy mechanism. 1968J. R. Manning Diffusion Kinetics for Atoms in Crystals i. 6 Two jumps of the interstitialcy are required to move an atom from one lattice site to another. |
