| Abstract: | Hillocks and voids (vacancy crystals) which were formed by electromigration on ultrapure gold and silver wires, showed only
the combined crystal forms {111} and {100}. These planes are identical with the equilibrium planes GI, calculated by Stranski and Kaishew for nonpolar substances under the assumption of only nearest neighbor interaction. Hillock
and void nucleation occurred on crystal imperfections (heterogeneous nucleation). Hillocks and vacancy crystals (voids) on
gold showed twin formation obeying the spinel law.
Dedicated to Professor I. N. Stranski on the occasion of his 80th birthday. |
