Current density-voltage characteristics in thin film Cu/CuO/Cu sandwich structure
(Facultad Experimental de Ciencias de la Universidad del Zulia, 2011)
Ion implantation inducing two-way shape memory effect in Cu-Al-Ni thin films
(Elsevier Science, 2019-11)
We report two-way shape memory effect (TWSME) induced by Al ion implantation in 6 μm thick Cu-Al-Ni thin films. The films display an average grain size of 3.7 μm and a martensitic transformation temperature (MS) of ≈ 240 ...
Thickness dependence of the martensitic transformation in textured Cu-Al-Ni thin films grown by sputtering on Si (001)
(Elsevier, 2019-06)
We study the thickness influence on the martensitic transformation in Cu-Al-Ni thin films grown by sputtering on Si (001). Thin films with thicknesses between 0.1 μm and 2.25 mm were grown at 563 K. The analysis of the ...
Development and characterization of shape memory Cu-Zn-Al thin films
(Elsevier Science, 2010-06)
Ternary Cu-Zn-Al alloys show good shape memory properties with narrow hysteresis and a wide range of martensitic transformation temperature (Ms), depending on the alloy composition. Thin films of Cu-Zn-Al with shape memory ...
Experimental and theoretical investigation of the electronic structure of Cu2O and CuO thin films on Cu(110) using x-ray photoelectron and absorption spectroscopy
(American Institute of Physics, 2013-01)
The electronic structure of Cu2O and CuO thin films grown on Cu(110) was characterized by X-ray photoelectron spectroscopy (XPS) and X-ray absorption spectroscopy (XAS). The various oxidation states, Cu0, Cu+, and Cu2+, ...
SEMICONDUCTING THIN FILMS OF CUSBS2
(Química Hoy, 2019)
Comparative study of ZnO thin films doped with transition metals (Cu and Co) for methylene blue photodegradation under visible irradiation
(MDPI AG, 2020-05)
We synthesized and characterized both Co-doped ZnO (ZnO:Co) and Cu-doped ZnO (ZnO:Cu) thin films. The catalysts’ synthesis was carried out by the sol–gel method while the doctor blade technique was used for thin film ...
Cross-Section Analysis of the Composition of Sprayed Cu 2 ZnSnS 4 Thin Films by XPS, EDS, and Multi-Wavelength Raman Spectroscopy
(Wiley VCH Verlag, 2018-12)
A detailed cross-section analysis of the chemical composition of sprayed Cu 2 ZnSnS 4 thin films is presented. X-ray diffraction (XRD), energy dispersive spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), and Raman ...
Smooth surfaces in very thin GdBa2Cu3O7-δ films for application in superconducting tunnel junctions
(Elsevier Science, 2015-03-15)
This paper provides a systematic analysis of the morphology and the superconducting critical temperature obtained in very thin GdBa2Cu3O7-δ films grown on (0 0 1) SrTiO3 substrates by DC sputtering. We find that the use ...
Copper nanoparticles synthesis in hybrid mesoporous thin films: Controlling oxidation state and catalytic performance through pore chemistry
(Elsevier Science, 2019-03)
The room temperature synthesis of copper (Cu) nanoparticles (NPs) supported within SiO2 mesoporous thin films (MTF) modified with either COOH or NH2 functional groups is reported. The functional groups present in the MTF ...
