    • Variable-range electron hopping, conductivity cross-over and space-charge relaxation in C60Br6 

      Manesh, Zachariah; Romanini, Michela; Zygouri, Panagiota; Gournis, Dimitrios; Tamarit Mur, José Luis; Barrio Casado, María del; Macovez, Roberto (2016-07-01)
      Article
      Accés obert
      Dielectric spectroscopy is employed to probe the frequency-dependent conductivity and dipolar dielectric response of solid C60Br6. Below approximately 215 K, charge conduction is electronic and well described by Mott's ...

    • Water-triggered conduction and polarization effects in a hygroscopic fullerene salt 

      Zachariah, Manesh; Tripathi, Pragya; Mitsari, Efstratia; Romanini, Michela; Zygouri, Panagiota; Gournis, Dimitrios; Barrio Casado, María del; Tamarit Mur, José Luis; Macovez, Roberto (2014)
      Comunicació de congrés
      Accés obert
      Impedance spectroscopy is employed to probe the frequency-dependent conductivity and dielectric response of the crystalline C60O24Na24 fulleride, both in its pure form obtained by heating to 473 K and in its bulk-hydrate ...

    • Water-Triggered Conduction Mediated by Proton Exchange in a Hygroscopic Fulleride and Its Hydrate 

      Zachariah, Manesh; Mitsari, Efstratia; Romanini, Michela; Zygouri, Panagiota; Gournis, Dimitrios; Barrio Casado, María del; Tamarit Mur, José Luis; Macovez, Roberto (2015-01-08)
      Article
      Accés obert
      Impedance spectroscopy is employed to probe the impact of water on the dc conductivity and ac dielectric response of the polycrystalline C-60(ONa)(24) fulleride, both in its bulk-hydrate form, stable only below 370 K, and ...
