Abstract

We have fabricated the flexible semitransparent pentacene-based thin-film transistors (TFTs) with poly-4-vinylphenol (PVP) dielectric layers which were deposited by spin coating on a thermostable plastic substrate with a conductive film. For the sourcedrain (SD) electrodes of our flexible pentacene TFTs both Au and semitransparent Ni Ox have been tested. It was found that Ni Ox was better matched to the pentacene channel for the SD contacts than Au. Our flexible pentacene TFTs with semitransparent Ni Ox contacts exhibited mobility of ∼0.24 cm2 V s higher than that achieved with Au contacts (∼0.14 cm2 V s) and also demonstrated a higher initial drain current.
