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.

By using organic semiconductor CuPc as photosensitive materials, we prepared an organic thin film transistor with the vertical structure consisted of metal Cu/ organic semiconductor CuPc/ Al/ organic semiconductor CuPc/ indium tin oxide ITO. CuPc semiconductor material has good photosensitive properties in the 700 nm light. When the light signal irradiates organic semiconductor photosensitive material, the electron-hole exciton is separated into photocurrent in built-in electric field produced by organic semiconductor material/ metal schottky contact. It transforms into the driving current of organic photoelectric triode. By using its current amplification effect, the output current increase obviously. The test result shows that the I-V characteristics of the transistor are obvious unsaturated triode characteristics. When using 700 nm light to irradiate the device, the working current of the device increases obviously.
