    Abstract: The presently disclosed subject matter can include or consist of the creation and manufacture of electrochromic thin film transistors, either self-sustaining or not, with lateral or vertical structure, deposited on any kind of functionalized substrate, referred to as electrochromic substrate, or non-functionalized substrate. The electrolyte material and the presence or not of an ultra-thin membrane can act as dielectric element. The electrochromic material can act as active semiconductor of the channel region. The gate, source and drain electrodes can be based on metal materials, such as Titanium, Gold, Aluminium, or degenerate semiconductive oxides, like Indium and Zinc oxide, Gallium-doped Zinc oxide. The device operation control process can be made by means of electronic and ionic current, and the off-state to on-state switch, or vice-versa, can be followed by a change of colour of the device.

  • Patent number: 8134149
    Abstract: The present invention has an object of providing a light emitting device including an OLED formed on a plastic substrate, which can prevent the degradation due to penetration of moisture or oxygen. On a plastic substrate, a plurality of films for preventing oxygen or moisture from penetrating into an organic light emitting layer in the OLED (hereinafter, referred to as barrier films) and a film having a smaller stress than that of the barrier films (hereinafter, referred to as a stress relaxing film), the film being interposed between the barrier films, are provided. Owing to a laminate structure of a plurality of barrier films, even if a crack occurs in one of the barrier films, the other barrier film(s) can effectively prevent moisture or oxygen from penetrating into the organic light emitting layer. Moreover, the stress relaxing film, which has a smaller stress than that of the barrier films, is interposed between the barrier films, thereby making it possible to reduce a stress of the entire sealing film.

  • Publication number: 20120049173
    Abstract: An organic field effect transistor (OFET) having a block copolymer (BCP) layer is provided. The OFET includes a gate, an optional dielectric layer, a BCP layer, an organic semiconductor layer, a drain, and a source. The BCP layer is formed between the dielectric layer and the organic semiconductor layer when the dielectric layer exists. Otherwise, the BCP layer is formed between the gate and the organic semiconductor layer when the dielectric layer does not exist. When being positioned between the gate and the organic semiconductor layer without the dielectric layer, the BCP layer also functions as a dielectric layer. Inclusion of the BCP layer enhances the electrical properties, such as the charge carrier mobility, of the OFET.

    Abstract: Disclosed is a method of manufacturing a multilayered thin film including a crystalline small molecular organic semiconductor layer and an insulating polymer layer for use in an organic thin film transistor through phase separation and annealing. The method includes applying a blend solution of organic semiconductor and insulating polymer on a substrate thus forming a vertically phase-separated thin film, which is then annealed so that the organic semiconductor contained in the insulating polymer layer is crystallized while being transferred to the surface layer. A high-performance organic thin film transistor fabricated using the same is also provided. The multilayered thin film in which the crystalline organic semiconductor layer is located on the insulating polymer layer through transfer and crystallization of the organic semiconductor can be used to fabricate the high-performance organic thin film transistor.
