Organic materials based on small conjugated molecules are typically large gap semiconductors. However, it has been observed that if two of these materials are in direct contact, they can exhibit enhanced electrical conductivity at the interface. The conductivity is originated from the charge transfer between two constituent materials. Therefore, this conductivity can be used to study the charge transfer effects. One of the very good tools to investigate such phenomena is single-crystal charge-transfer interfaces. In this research work, we build and investigate Rubrene single-crystal based charge-transfer interface devices with new interesting acceptor materials such as fullerenes and hexacyano-[3]-radialene anion-radical material family. Here, we present different ways of fabricating these interface devices, i.e., thermal evaporation, drop-casting, spin coating, and shear coating as well as discuss the electrical properties of these interfaces. This work is financially supported by DFG KR 4364/4-1.
