Theme 4: Electronic and electrostatic properties, charge transfer

Coordinators: Clemens BARTH (CINAM, Marseille) et Sylvie GODEY (IEMN, Lille)

Objectives

  • Work function measurements at nano-objects (e.g., metal nanoparticles) and self-assembled molecular nanostructures
  • Measurements of charges and dipoles inside complex systems and of charged single atoms or molecules
  • Electronic properties of materials for photovoltaics
  • Charge transfer into insulator supported nano-objets (atoms, molecules, nanoparticles, …) and charge transfer between such nano-objects

Experimental techniques

  • AFM non-contact (NC-AFM)
  • Electrostatic force spectroscopy (EFS) as a function of the tip-surface bias voltage
  • Kelvin probe force microscopy (KPFM) implemented into nc-AFM
  • Time resolved dynamics of charging and discharging phenomena
