    • Abstract

       

      In this study, iron phthalocyanine (FePc) thin films were obtained by spin-coating at 80°C and used as the active layer in organic thin-film transistors (OTFTs). The OTFTs have an inverted coplanar structure and were fabricatedon plastic substrates made of polyethylene terephthalate. Silicon oxide spin-on glass was used as gate dielectric. The FePc thin films were characterized by UV-Vis spectroscopy, Raman spectroscopy and current–voltage measurements. Interestingly, the electrical characteristics of the FePc OTFTs exhibited a depletion-type behaviour. The threshold voltage extracted was -1.18 V, the subthreshold slope was 0.1 V per decade and the field-effect mobility was 0.002 cm$^2$ Vs$^{-1}$. As far as we know, this is the first report of FePc-based OTFTs on plastic substrates.
