Polymer/YOx Hybrid‐Sandwich Gate Dielectrics for Semitransparent Pentacene Thin‐Film Transistors Operating Under 5 V

A hybrid-sandwich dielectric—combining the advantages of inorganic high-dielectric-constant dielectrics and ultrathin organic dielectrics—for the gate of pentacene thin-film transistors (TFTs, see figure) is presented. The performance of the TFTs and resistance-load inverters constructed with them is shown to be satisfactory even when the devices are operated at the low voltage of –5 V.
