College 7

Spectroscopy in solid state physics & chemistry

College Secretary: Mohamed Zbiri

The activities of College 7 reflect the strong advancement made in the employed solid state neutron-based spectroscopic techniques (experimental and computational), at both the user groups and the ILL in-house science levels.

Seminars

If you wish to give a College 7 seminar at the ILL, please contact Mohamed Zbiri.

Keywords

7-01 Lattice dynamics

  • harmonic excitations (density of states, phonon dispersion)
  • anharmonicity (frequency shifts and phonon line shapes)
  • electron phonon coupling
  • disorder effects (local modes, hybridization, frequency shifts and broadening)
  • excitations in quasi crystals

7-02 Dynamics of structural phase transitions

  • critical scattering
  • soft modes
  • central peaks
  • modulated phases

7-03 Ionic relaxation and ionic diffusion in the solid state (except liquids and glasses)

  • self-diffusion and demixing
  • guest dynamics in a host structure
  • guest-host coupling

7-04 Spectroscopy of (nonmagnetic) molecular systems

7-05 Spectroscopy of chemi- and physisorbed species
