Water‐Assisted Growth: Optimizing the Optoelectronic Properties of Face‐On Oriented Poly(3,4‐Ethylenedioxythiophene) via Water‐Assisted Oxidative Chemical Vapor Deposition (Adv. Funct. Mater. 14/2021)

In article number 2008712, Meysam Heydari Gharahcheshmeh, Karen K. Gleason, and co‐workers present remarkable texture and nanostructural engineering of poly(3,4‐ethylenedioxythiophene) (PEDOT) thin films grown by water‐assisted oxidative chemical vapor deposition, which yields a record high electrical conductivity of 7520 S/cm. In PEDOT thin films with a highly face‐on orientation, the charge transport between chains becomes a rate‐limiting factor. Thus, electrical conductivity enhancement is achievable by reducing the π–π stacking distance through tuning the process parameters.
