Organic diodes with highly improved charge injection and transport via one-pot treatment process

A gap-type diode with an organic semiconductor is demonstrated in order to demonstrate the effect of charge injection on transport in the bulk region of the organic semiconductor. It is simply incorporated as a basic component of organic field-effect transistors, which plays, in particular, as a diode in terms of electrical characteristics at the critical voltage regime over fully injected charge carriers, similar to a sandwich-type diode structure in organic light emitting diodes and organic photovoltaic cells. In this work, a current at least 20 times higher than that obtained with other treatments or with no treatment was shown in the diode with 1H,1H,2H,2Hperfluorooctyl-trichlorosilane treatment on the Au metal contacts. It was clearly found that charge injection induces a substantial enhancement of charge transport in organic diodes.
