Abstract:In organic-based electronics, interfacial properties have a profound impact on device performance.
The lineup of energy levels is usually dependent on interface dipoles, which may arise from charge
transfer reactions. In many applications, metal-organic junctions are prepared under ambient
conditions, where direct overlap of the organic system from the metal bands is prevented due to
presence of oxides and/or hydrocarbons. We present direct experimental and theoretical evidence
showing that the interface energetic for such systems is governed by exchange of an integer amount
of electrons.
