Abstract

The growth morphology of thin Cd 3As 2 films on NaCl substrates has been described. It was found that growth of the films begins with the formation of three-dimensional nuclei. The dependence of both number density and size of such nuclei on condensation parameters was investigated. In addition, nucleus size distributions, number densities of nuclei, saturation densities and initial nucleation rates were analysed on the basis of theoretical expressions. Values for the activation energies of adsorption and surface diffusion and for the binding energy of a pair of atoms were estimated.
