Band-bending in organic semiconductors: the role of alkali-halide interlayers.

Haibo Wang1, Patrick Amsalem, Georg Heimel, Ingo Salzmann, Norbert Koch, Martin Oehzelt.   

Abstract

Band-bending in organic semiconductors, occurring at metal/alkali-halide cathodes in organic-electronic devices, is experimentally revealed and electrostatically modeled. 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.
