The role of composition, structure and morphology on the electrical, optical an...
Borges, Joel; Martin, N.; Barradas, N. P.; Alves, E.; Eyidi, D.; Girardeau, T.; Fonseca, C.; Vaz, F.; Marques, L.Metallic (Me) oxynitrides (MeNxOy) are an attractive class of materials due to a unique set of versatile properties in different technological domains such as protective applications (wear, diffusion and corrosion-resistance), decorative coatings, gas barriers, microelectronics, optoelectronics, solar cells, etc. Among the group of oxynitrides, aluminium oxynitride (AlNxOy) presents some interesting characteris...
Atomic environment and interfacial structural order of TiAlN/Mo multilayers
Tavares, C. J.; Rebouta, L.; Rivière, J. P.; Girardeau, T.; Goudeau, Ph.; Alves, E.; Barradas, N. P.Multilayered TiAlN/Mo coatings were deposited by dc reactive magnetron sputtering in a custom-made chamber. In order to assess the composition of these coatings, a combined study of Extended X-ray Absorption Fine Structure (EXAFS) and Rutherford Backscattering Spectrometry (RBS) experiments were performed. Through the simulation of the EXAFS spectra, giving the local environment of the titanium atoms inside the...
