During electrochemical investigation of TiN coatings, in an H2SO4 solution, we observed that the samples maintained under a 1200 mV (SSE) polarization for 1 h which were initially golden yellow became roseate, the reasons for this modification probab

A spectrophotometer is described which allows specular reflectance measurements at near normal and oblique incidence (30-44-60-75 degrees ). The samples can be heated up to 800 degrees C. The spectral range extends from 0.22 to 6.0 mu m. Reflectivity

Reflectance of stoichiometric ZrN was investigated from 0.22 to 5.50 eV as a function of temperature between 20 and 700 °C. The complex dielectric function was calculated by a Kramers–Kronig analysis and split to find the interband and intraband c

The optical properties of titanium nitrides and carbonitrides have been studied. The data are analyzed by the Drude-Lorentz model of the dielectric function and interpreted with a simple semirigid bands model of the electronic structure of these mate

The d.c. electrical resistivity ϱ and Hall constant RH of ZrNx films, deposited in a reactive sputtering system, were measured as a function of n nitrogen partial pressure P(N2). Film structure was also examined by X-ray diffraction. ϱ showed a dis

On présente des résultats préliminaires sur l'évolution des propriétés optiques des nitrures et des carbonitrures de titane avec leur composition. On montre que les résultats obtenus sont conformes à un modèle de leur structure électronique

A new investigation of the optical properties of scandium is presented. Near-normal-incidence reflectivity measurements were performed from 0.22 to 5.5 eV on polycrystalline thin films evaporated in situ in ultrahigh vacuum. The reflectivity, from 0.

Likeness and proximity are studied in the particular context of geographical discontinuity, in both clustered (bounded) and continuous spaces. First, likeness and proximity are linked: likeness could be spatial and/or social; moreover, social structu
