Micro- and Nanopatterning of Highly Conductive PEDOT Thin Films.

ABSTRACT: This work presents two fabrication strategies for the development of organic thin-film devices at the micro- and nano-scales. We make use of non-commercial PEDOT synthesized via liquid-phase oxidative chemical polymerization, using vanadium pentoxide (V₂O₅) as a oxidant. The optimization of this synthetic technique enables the production of homogeneous PEDOT films with a controlled thickness and tunable electrical properties. At the micro-scale, we fabricate a PEDOT microstripe with gold contacts using standard optical lithography and confirm the high electrical performance of the processed PEDOT device. Moreover, at the nanoscale we apply a self-assembling technique, namely the nanosphere lithography, to pattern the thin film over a large area with a hexagonally clos
