In this report, we describe rectification characteristics of a dual-layered organic device sandwitched with Au electrodes. Triphenylamine derivatives are commonly used in organic photoconductors as hole-transport materials for laser-beam printers. In the photoconductors, photogenerated holes are injected easily from a carrier generation layer to the hole-transport layer (HTL). However, in the case of metal/HTL/metal device, it is needed a high voltage for injecting a hole to the HTL even when Au electrode having a large work function is used. For realizing an ohmic contact, we employed a structure of Au/triphenylamine derivative (TPA; the molecular structure is shown in Fig. 1) doped with C60. Then, a metal/TPA/C60-doped TPA/metal was prepared and its rectification property was measured.
