Electrodes formation method has been found to be very important in electronic devices using ferroelectric P(VDF-TrFE) copolymer. Depending on the deposition system used, vacuum-based deposition methods such as e-beam or thermal evaporation of metal electrodes has resulted in the performance deterioration, due to damages on the fragile organic surface by highly energetic particles such as intensive short-wavelength radiation, secondary electrons, etc. On the other hand, the transfer-printing of electrodes, which is formed on other substrates, onto the organic surface does not involve any such damages, leading to high-performance devices. Further, the transfer-printing process allows additional advantages of electrode surface tailoring or device fabrication on non-flat micro-rough surfaces. The proposed technique has led to much better performance of InGaZnO-based non-volatile memory transistors, compared to devices based on the direct evaporation of metal electrode. Transfer-printing of electrodes, instead of direct vacuum-based deposition, may lead to higher performing devices based on other organic electronic materials.
