High-performance transistors and complimentary inverters based on solution-grown aligned organic single-crystals

Abstract: Field-effect-transistors (FETs) fabricated from organic single crystals show the highest charge carrier mobility among organic semiconductors. However, single crystals are less frequently considered for complementary circuits composed by basic units of inverters1-4. Constructing a complementary inverter is technically more complex as both p- and n-channel transistors are required to be patterned onto a common substrate. Here, we report a simple solution processing method to fabricate complementary inverters based on n-channel C60 single crystals and p-channel 6,13-bis(triisopropyl-silylethynyl) pentacene (TIPS-pentacene) single crystals. We achieved a signal gain as high as 155. Hence, this work provides a platform to study high-performance complementary circuits based on organic single-crystals.
