The P3AT film exhibited large optical dichroic ratio, which originated in the polymer backbones aligned to the drawing direction. In-plane anisotropy and enhancement of FET characteristics have been observed that are caused by molecular alignment. In the case of poly(3-dodecylthiophene), the hole mobility along the drawing direction was enhanced by a factor of 25 compared with that of spin-coated film.}, pages = {4608--4610}, title = {Polymer field-effect transistors by a drawing method}, volume = {84}, year = {2004}, yomi = {ナガマツ, シュウイチ and タカシマ, ワタル} }
