Fermi-level pinning of C60 (sub)-monolayers on a sexithiophene (6T) bilayer grown on Ag(111) is shown to induce electron transfer from the metal to a fraction of the C60 molecules. The electrostatic potential resulting from the charge transfer process is responsible for a potential drop within the 6T interlayer and, more remarkably, for dipole-dipole repulsion, leading to a disproportionation into coexisting neutral and charged C60 molecules. We suggest that charge ordering phenomena may occur… Expand

Organic semiconductor density of states controls the energy level alignment at electrode interfaces

Band-bending in organic semiconductors: the role of alkali-halide interlayers.
TLDR
Metal-to-organic charge transfer through the insulator, rather than doping of the organic by alkali-metal ions, is identified as the origin of the observed band-bending, which is in contrast to the localized interface dipole occurring without the insulating buffer layer. Expand

TLDR
Surprisingly, although in most cases the pinning occurs only when the metal is present, it is not related to charge transfer between the electrode and the organic layer, and charge rearrangements at the interface between the SAM and the OSC are observed. Expand
