Project Details

Description

Since its inception, the scientific and academic activity on the solid state has focused mainly on the preparation, characterization and theoretical studies of the properties of different types of materials with potential technological applications. in particular, there is a strong interest in coatings manufactured with materials that can be broadly classified as: semiconductors, superconductors, dielectrics, hard coatings, etc. a considerable effort has been made by the scientific community in the formation, characterization and study of nitrides with noble metals of the sawdust 4d and 5d, such as au, ag, cu and ru, which may have interesting electrical and mechanical properties [27]. on the other hand, transition metal nitrides have a great interest in fundamental sciences and technical applications,since these transition metal nitrides have such diverse properties ranging from appreciable changes in their hardness to the presence of superconducting properties [28].

Objective

Production of run coatings by varying the temperature of the substrate at the time of discharge, in order to carry out a study on growth conditions based on ruxn stoichiometry. specific -make run coatings by the magnetron sputtering technique, varying the temperature of the substrate. -obtention of narrow spectra n1s and ru by means of x-ray photoelectron spectroscopy. -obtention of x-ray diffraction patterns.- morphological characterization of the coatings by means of scanning electron microscopy.

Expected results

Preparation technique and equipment to carry out thin film coatings by means of the reactive cathodic sputtering technique, an industrial ajax system will be used, the growth chamber has a base pressure of 10-8 torr. the gases for the coatings are introduced through digital flow meters that are controlled from a computer. this camera has a window through which optical spectroscopy of plasma produced during deposits can be made. to carry out the xps studies, we have a double-anode x-ray source, an aluminum source and a magnesium source, whose energies are derived from the k? transitions. from the anode of al photons are obtained with an energy of 1486.6 ev and a line width of 0.85 ev and for the anode of mg photons are obtained with an energy of 1253.6 ev and a line width of 0.5 ev brand specs. the x-ray diffraction studies will be carried out with the bruker axs diffractometer (d8 advanced) geometry with parallel beam optics, using a 40 kv and 30 ma radiation and grazing incidence at a 2 ° angle. for the semi - quantitative and morphological elemental analysis there is a philips xl 30 feg dispersive energy spectrometer (eds) with a standard edax probe, which performs analysis in a region of 1?m2. the images are obtained by means of an optical-electronic system.for the semi - quantitative and morphological elemental analysis there is a philips xl 30 feg dispersive energy spectrometer (eds) with a standard edax probe, which performs analysis in a region of 1?m2. the images are obtained by means of an optical-electronic system.for the semi - quantitative and morphological elemental analysis there is a philips xl 30 feg dispersive energy spectrometer (eds) with a standard edax probe, which performs analysis in a region of 1?m2. the images are obtained by means of an optical-electronic system.
