Tuning the charge injection of P3HT-based organic thin-film transistors through electrode functionalization with oligo-phenylene SAMs
Emanuele Orgiu, Núria Crivillers, Jürgen Rotzler, Marcel Mayor, and Paolo Samorì, London (2010)
Field-effect mobility and threshold voltage are modulated by functionalizing gold electrodes with chemisorbed SAMs of aromatic thiols having an increasing number of phenylenes. The contact resistance in poly(3-hexylthiophene)-based TFTs was found to be ruled by the joint effect of the energetic alignment between metal and semiconductor, the interfacial morphology and tunneling resistance of the SAMs.
