Effect of substrate temperature on vapor-phase self-assembly of n-octylphosphonic acid monolayer for low-voltage organic thin-film transistors

This research is the result of a collaboration (since 2011) between University of Strathclyde (Institute for Pharmacy and Biological Sciences, and Electronic and Electrical Engineering) and the University of West Bohemia, Czech Republic. The research reported new insights into the vapour-phase self-assembly of organic monolayers based on short alkyl phosphonic acids. The simplicity of the process has led to engagement on this work with University of Oxford [hazel.assender@materials.ox.ac.uk] in June of 2013. We have deposited the monolayers onto their dielectric materials to aid in the development of a roll-to-roll transistor fabrication process. Five-fold improvement in the mobility was achieved.
