| contents | Characterization of new copper sulfide materials C. Cruz Vázquez R. Bernal M. Inoue M. B. Inoue F. J. Espinoza Beltrán Física, Astronomía y Matemáticas We have reported that the slow reaction between a very stable copper complex, [Cu(cyclam)](ClO4)2 (cyclam: 1, 4, 8, 11 tethraazacyclotetradecane), and Na2S provides a new amorphous copper sulfide, which precipitates in the form of a dark powder, adhering a part of the compound in the form of a thin film on the walls of the reaction vessel. A CuS thin film deposited on a polyethylene substrate showed a metallic like electrical behavior down to 250 K, and was transparent in mthe visible region of the spectrum. In this work we report the chemical modification of the resulting amorphous copper sulfide. The film and the powders were chemically treated with alkali metal iodides. In addition, the films were treated with iodine in an organic solution. In such a way, the electrical properties of the films were notoriously improved. We report the characterization of the films and powders by using X - ray diffraction, and X-ray photoelectron spectroscopy (XPS) and electrical conductivity measurements 1999 artículo científico 1665-3521 https://www.redalyc.org/articulo.oa?id=94200957 en http://www.redalyc.org/revista.oa?id=942 Superficies y vacío application/pdf Sociedad Mexicana de Ciencia y Tecnología de Superficies y Materiales A.C.
