    • Crystal structure, Raman scattering and magnetic properties of CuCr2-xZrxSe4 and CuCr2-xSnxSe4 selenospinels 
      Pinto, C.; Galdámez Silva, Antonio; Barahona, P.; Moris, S.; Peña, O. (Elsevier, 2018)
      Selenospinels, CuCr2-xMxSe4 (M = Zr and Sn), were synthesized via conventional solid-state reactions. The crystal structure of CuCr1.5Sn0.5Se4, CuCr1.7Sn0.3Se4, CuCr1.5Zr0.5Se4, and CuCr1.8Zr0.2Se4 were determined using ...
    • Magnetic properties and crystal structure of solid-solution Cu2MnxFe1-xSnS4 chalcogenides with stannite-type ... 
      López-Vergara, F.; Galdámez, A.; Manríquez, V.; Barahona, P.; Peña, O. (Wiley-VCH Verlag, 2014)
      New solid solutions Cu2MnxFe1-xSnS4 were prepared by direct combination of the corresponding elements at 850°C. The crystal structure of Cu2Mn0.4Fe0.6SnS4 was determined by single-crystal X-ray diffraction. This phase is ...
    • Physical properties of layer-type MPS3 compounds: M0.5In0.33PS3 (M=Cd, Fe, Mn) 
      Manríquez, V.; Barahona, P.; Pea, O.; Mouallem-Bahout, M.; Avila, R. E. (2001)
      Cd0.5In0.33PS3, Fe0.5In0.33PS3, Mn0.5In0.33PS3, and compounds have been synthesized by ceramic method at 923 K. These compounds were characterized by powder X-ray diffraction (XRD), Fourier transform infrared (FTIR), ...
    • Raman characterization of CuCr2-xSnxS4 spinels 
      Valencia-Gálvez, P.; Peña, O.; Moris, S.; Barahona, P. (Sociedad Chilena de Quimica, 2019)
      Polycrystalline thiospinels CuCr2-xSnxS4 (x = 0.4, 0.8, 1.0 and 1.4) were synthesized via conventional solid-state reaction. The samples were characterized by powder X-ray diffraction (XRD), energy-dispersive X-ray analysis ...
    • Raman characterization of CuIrSnX4 normal-spinel systems 
      Barahona, P.; Galdámez Silva, Antonio; Valencia Gálvez, P.; Moris, S (Natl Inst R&D Materials Physics, 2020)
      CuIrSnS4, CuIrSnSe4 and CuIrSnS2Se2 were synthetized by a solid-state reaction at 700 degrees C. Powder X-ray diffraction patterns were consistent with normal spinel-type structure. Scanning electron microscopy (SEM-EDS) ...
    • Vibrational and optical properties of CZTS derivatives for photovoltaic applications: Synthesis of ... 
      Pinto, C.; López, F.; Galdámez, A.; Barahona, P.; Moris, S. (Elsevier Masson SAS, 2018)
      © 2018 Elsevier Masson SAS Herein, we report the vibrational and optical properties of new Cu2ZnSn1-xGexS2Se2 solid solutions prepared by isomorphic substitution of a fraction of Se by S in Cu2ZnSn1-xGexSe4 (CZTGeSe) through ...
