Abstract

Organic donor/acceptor bilayers form a two-dimensional charge sheet composed of electron-hole pairs at their heterointerfaces due to formation of charge-transfer (CT) complexes. The CT induces electron-hole pairs which are useful for carrier transport in both vertical and lateral direction, providing novel electronic device applications. Here, we fabricated a two-dimensional charge sheet using organic donor/acceptor heterointerfaces and investigated its electrical behavior. Further, we revealed that conductive CT interfaces are generated by stacking almost monolayer of donor and acceptor thin films. These novel charge induction mechanisms will provide a new principle for designing organic devices.
