Abstract
The evaporative spray deposition using ultradilute solution (ESDUS) technique enables layer-by-layer and pixel-by-pixel deposition of polymer semiconductors. In this study we prepared thin films of dioctylfluorene-co- bithiophene) alternating copolymer, F8T2, by ESDUS and by a conventional spin-coat. These films were made into fabricated field effect transistors to investigate carrier transportation properties. Since the organic films were formed by deposition of aerosol particles in ESDUS, the carrier transportation properties in ESDUS films had been expected lower than those in spin-coat films, which are formed through spread polymer solution. However, the device performance was almost identical, indicating that the polymer deposited as particles undergoes rearrangement process on the substrate.
