  • High-pressure Raman scattering study of defect chalcopyrite and defect stannite ZnGa2Se4 
    VILAPLANA, R.; GOMIS, O.; PÉREZ-GONZÁLEZ, E.; ORTIZ, H. M.; MANJÓN, F. J.; RODRÍGUEZ-HERNÁNDEZ, P.; MUÑOZ, A.; ALONSO-GUTIÉRREZ, P.; SANJUÁN, M. L.; URSAKI, V. V.; TIGINYANU, I. M. (AIP Publishing LLC, 2013)
    High-pressure Raman scattering measurements have been carried out in ZnGa2Se4 for both tetragonal defect chalcopyrite and defect stannite structures. Experimental results have been compared with theoretical lattice dynamics ...
  • Thermally activated cation ordering in ZnGa2Se4single crystals studied by Raman scattering, optical absorption, andab initiocalculations 
    VILAPLANA, R.; GOMIS, O.; PEREZ-GONZÁLEZ, E.; ORTIZ, H. M.; MANJÓN, F. J.; RODRIGUEZ-HERNANDEZ, P.; MUŇOZ, A.; ALONSO-GUTIÉRREZ, P.; SANJUÁN, M. L.; URSAKI, V. V.; TIGINYANU, I. M. (IOP Publishing, 2013)
    Order–disorder phase transitions induced by thermal annealing have been studied in the ordered-vacancy compound ZnGa2Se4 by means of Raman scattering and optical absorption measurements. The partially disordered as-grown ...
  • Vibrational properties of CdGa2S4 at high pressure 
    GALLEGO-PARRA, S.; GOMIS, O.; VILAPLANA, R.; ORTIZ, H. M.; PÉREZ-GONZÁLEZ, E.; LUNA, R.; RODRÍGUEZ-HERNÁNDEZ, P.; MUÑOZ, A.; URSAKI, V. V.; TIGINYANU, I. M.; MANJÓN, F. J. (AIP Publishing LLC, 2019)
    Raman scattering measurements have been performed in cadmium digallium sulphide (CdGa2S4) with defect chalcopyrite structure up to 25 GPa in order to study its pressure-induced phase transitions. These measurements have ...
