Abstract

We report a 6,13-Bis(triisopropylsilylethynyl)-pentacene (TIPS-pentacene) solution-processed high-voltage organic thin film transistor (HVOTFT) with a large breakdown voltage of |VDS| > 450 V, a three-fold increase from previous results. An offset channel architecture and an organosilane-based self-assembled monolayer (SAM) treatment were used to achieve large breakdown voltages. Solution-processed HVOTFTs will enable novel high-voltage and flexible applications. Reliability of the HVOTFT under high-field stress was studied in the context of threshold and onset to conduction voltages.
