Crystal structure and Raman scattering characterization of Cu2Fe1- xCoxSnS4 chalcogenide compounds López Vergara, Fernanda; Galdámez Silva, Antonio; Manríquez Castro, Víctor; González Morales, Guillermo (Elsevier, 2015)This work reports the synthesis by solidestate reaction of Cu2Fe1-xCoxSnS4 solid solutions. Crystal structures of Cu2Fe0.8Co0.2SnS4 and Cu2Fe0.6Co0.4SnS4 were investigated by single crystal X-ray diffraction. Both phases ...

López Vergara, Fernanda; Galdámez Silva, Antonio; Manríquez Castro, Víctor; Barahona Huenchumil, Patricia Mabel; Peña, O. (Wiley, 2014)New solid solutions Cu2MnxFe1 xSnS4 were prepared by direct combination of the corresponding elements at 850 8C. The crystal structure of Cu2Mn0.4Fe0.6SnS4 was determined by single-crystal X-ray diffraction. This phase ...

Galdámez Silva, Antonio; López Vergara, Fernanda; Barahona Huenchumil, Patricia Mabel; Manríquez Castro, Víctor; Avila, Ricardo E. (Springer, 2012)The new solid solutions AgPbSb1−xBixS3 were prepared by solid state reactions. The phases were characterized by powder X-ray diffractions (XRD), scanning electron microscopy, and thermal analysis. The XRD patterns of ...
