Abstract
The growth of copper island films on the Si(100)-c(4 × 12)-Al surface phase has been studied using scanning tunneling microscopy (STM). The dependence of the island concentration on their size and the substrate temperature is determined. The diffusion activation energy and the binding energy of copper dimers are determined from an analysis of the experimental STM data in terms of the kinetic theory of nucleation. The critical temperature corresponding to a change in the growth regime is evaluated from an Arrhenius plot. It is established that the c(4 × 12)-Al surface phase exhibits an orienting action on the crystalline structure of Cu nanoislands.
