We have easily fabricated channel patterns of organic field-effect transistors (OFETs), in which channel lengths were 5μm, by using wet-spun poly(3,4-ethylenedioxythiophene)/poly(4-styrenesulfonate) (PEDOT/PSS) microfibers with diameters of ca. 5μm. Pentacene-based FETs with a top-contacted configuration, showed a hole mobility of 0.13cm 2 V −1 s −1 and on/off current ratio...
Highly conductive microfibers made of poly(3,4-ethylenedioxythiophene) doped with poly(4-styrenesulfonate) (PEDOT/PSS) were fabricated by wet-spinning and subsequent dip-treatment in ethylene glycol. The electrical conductivity of the PEDOT/PSS microfibers with a diameter of ca. 5μm was significantly increased from 74Scm −1 to 467Scm −1 by the dip-treatment in 3min. The result was...
