Research topics:

  • X-Rays Absorption Spectroscopy: effects of thermal disorder on EXAFS spectra
    • Cumulant method for EXAFS data analysis: strengths and limitations
    • Complementarity of EXAFS and diffraction: bond thermal expansion and lattice thermal expansion
    • Parallel and perpendicular mean square relative displacements: correlation effects, anisotropy of relative atomic vibrations
    • Isotopic effect on EXAFS Debye-Waller factor and on bond thermal expansion
    • "EXTRA" software package fior EXAFS analysis, specifically tailored for the 1st-shell analysis by the ratio method and for the interpretation of cumulants
  • Negative thermal expansion (NTE) in solids, study of the local mechanisms
    • Diamond and zincblende structures: Ge, CdTe and CuCl. Isotropic NTE.
    • Cuprite framework structures: Cu2O and Ag2O. Isotropic NTE. Linear O-M-O link (M=Cu, Ag)
    • Delafossite structures: CuScO2 and CuLaO2. Anisotropic NTE. Linear O-Cu-O link
    • Investigations of the relations of bond expansion and perpendicular MSRD with the phenomenological models of NTE based on the competition between bond stretching and tension effects
  • Local structure and dynamics in disordered solids
    • AgI-doped fast-ion-conducting silver-borate and silver-molybdate glasses
    • Local environment of III-V impurities in amorphous germanium thin films
  • Local structure and dynamics of metal clusters
    • EXAFS on Rh nano-clusters supported on carbon (collab. with C. Lamberti and G. Agostini, Torino)
