Wet-Processable Electronic Materials Potentially Available to Organic Field-Effect Transistors

First, this article briefly describes our recent efforts on fabrication of organic field-effect transistors. We then describe our researches on wet-processable electronic materials such as colloidal dispersion of SrTiO3 nanoparticles and poly(3,4-ethylenedioxythiophene /poly(4-styrenesulfonate) (PEDOT/PSS) colloidal dispersion, which are potentially available to organic field-effect transistors as high-dielectric-constant insulators and source-drain/gate electrodes, respectively. In this article we also briefly review recent patents on organic electronic devices, contributed by other research groups.
