In this work a single Langmuir probe has been used to determine in-situ the plasma electronic temperature (T e ) and the electronic density (h e ) of an rf magnetron sputtering system used to grow CN x films. Sodium chloride substrates and a carbon target (99.999%) in a mixture of Ar/N 2 were used.

Abstract
By the analysis of Xβray reflectivity angle dependence the existence of a characteristic nucleus height h in the island stage of nickel growth have been found. As the condensation time Ο rises, the value of h increases according to a linear law, and the portion of substrate surface occupied by nuclei is described by a curve with saturation. The formation latent period of the fraction with preferential size h is extremely small, that, in principle, allows to produce smooth surfaces, even if the effective thickness is only about several atomic layers. The kinetic characteristics are identical both at growing on monocrystalline silicon and amorphous SiO~x~ substrates.
