摘要
Devices with two hole-blocking electrodes have been constructed to investigate the transport of electrons in a poly(dialkoxy-p-phenylene vinylene) (PPV) derivative. In order to test the compatibility with the solution processed PPV, a variety of hole-blocking bottom electrodes are applied and the absence of hole transport has been verified. The electron transport in PPV is strongly reduced as compared to the hole transport and exhibits a strong dependence on the applied voltage as well as sample thickness. These results are indicative for trap-limited electron transport with the energy of the trapping sites described by an exponential distribution.
