Abstract

(Figure Presented) Pentacene-based thin-film transistors (TFTs) are fabricated, and characterized, on UV-curable polymer gate dielectrics with different photocrosslinking times (hence, different degrees of crosslinking). The results show that pentacene TFT measurements can be an informative probe of polymer film viscoelastic properties, as modified by crosslinking, and relatively mild, contactless polymer dielectric processing can dramatically enhance the OTFT performance.
