ABSTRACTWe 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.

ABSTRACTA 6,13-Bis(triisopropylsilylethynyl)pentacene (TIPS-pentacene) based high-voltage organic thin film transistor (HVOTFT) has been demonstrated via a low temperature (< 100°C) solution-processed fabrication method on borosilicate glass. High-voltage is an area not well developed in the organic transistor field and can be of benefit to various applications requiring such an operating range beyond that of conventional thin film transistors. Here, our HVOTFT exhibited a mobility μ of 0.005 cm2 V-1 s-1 and a breakdown voltage of VDS > 120 V, the latter being due a space-charge limiting device architecture in which the channel is partially gated. Non-saturating I-V characteristic behavior was observed. This is in contrast with our vacuum-deposited pentacene HVOTFTs which exhibited breakdown voltages of VDS > 400 V. TIPS-pentacene was grown via a drop-casting deposition, with its crystallinity and grain size deduced under XRD and SEM analysis. The HVOTFT was fabricated with a dielectric stack of a high-k Bi1.5Zn1Nb1.5O7 (BZN) and parylene-C.
