Title
Optimization of the Vapor Phase Polymerization of PEDOT:Tosylate
Abstract

Poly(3,4-ethylenedioxythiophene) (PEDOT) is an organic semiconductor routinely used in applications such as organic electrochemical transistors (OECTs), thin film transistors (TFTs) and biosensors. These devices suffer from numerous performance limitations such as low conductivities and delamination in analytic solutions. PEDOT doped with p-toluenesulfonate (PEDOT:Tosylate) has been shown to overcome many of these drawbacks, however the optimal parameters in the vapor deposition process have yet to be found. By using a novel cluster tool developed by ReynoldsTech, each step in the deposition of PDOT:Tosylate thin films can be carefully controlled to produce consistent and reliable results. The new cluster tool provides a stable processing environment to maintain consistency between experiments. Parameters in the deposition process are examined and co-optimized to produce highly conducing PEDOT:Tosylate films. Initial results demonstrate that conducting thin films can be produced with this machine and show significant promise for improvement in the future.
