087 Influence of grystallite size on thermo- and electro- conductivities of nanodiamond coating |
Authors: | S.F. Dudnik, A.I. Kalinichenko, V.E. Strel'nitskij | |
Summary: | Dependence of thermo- and electro- conductivities of nanocrystalline diamond coating on crystalline size and boundary layer depth is theoretically investigated. Nanodiamond is considered as two-phase material composed of dielectric diamond grains segregated bythin graphite layers with electronic conductivity. Derived expressions for thermoconductivity and resistivity show accordance with
experimental data.

087 Nanocrystalline CVD diamond films: structure, properties and application prospects |
Authors: | Vyrovets I. I., Grіtsyna V. I., S. F. Dudnik, O. A. Opalev, Reshetnyak E. N., Strelnitskiy V. E. | |
Summary: | The review of the literature data devoted to manufacture of CVD-nanocrystalline diamond films have been per-formed. The basic technological processes that allow limiting the size of growing diamond crystallites (pretreatment of a substrate surface, change of working gas species and use of substrate bias potential) were discussed. Structure, properties, future prospects of nanocrystalline diamond film application in various areas of science and engineering was given. | |

087 Features of morphology of diamond coatings with nanocrystalline structure |
Authors: | V.I. Gritsyna, S.F. Dudnik, O.A. Opalev, E.N. Reshetnyak, V.E. Strel’nitskij | |
Summary: | Results of researches of morphology of nanocrystalline diamond coatings deposited from gas phase in a wide range of conditions of their synthesis are given. Depending on conditions of their deposition several morphological types of a surface structure – globular and lamellar is possible. Studies of the coatings roughness with different morphological structure have shown that the lamellar type structure is more preferable to get nanocrystalline diamond coatings with the minimal roughness. | |

087 CURRENT ON GROWTH KINETICS OF NITROGEN-DOPED NANOSTRUCTURED DIAMOND COATINGS |
Authors: | Gritsyna V.I., Dudnik S.F., Koshevoi K.I., Opalev O.A., Strel'nitskij V.E. | |
Summary: | The experimental results of investigations of the influence of the discharge current value and composition of the gas phase with a relatively low content of argon on the kinetics of the synthesis process in glow discharge plasma of nitrogen-doped nanostructured diamond coatings have been discussed. It was shown that under feeding of nitrogen into the gas phase by a corresponding decrease of hydrogen concentration the growth rate of nanostructured diamond coatings can increase or decrease depending on the relative concentrations of the gas phase components. The analysis and comparison of the experimental data with the available literature data of the gas phase composition, the discharge power (temperature) on the kinetics of diamond coating synthesis have been performed. | |
