Improved pentacene growth continuity for enhancing the performance of pentacene-based organic thin-film transistors

► The proposed alternative pBC structure can improve growth continuity of pentacene. ► The improved growth continuity of pentacene reduces the contact resistance of device. ► The bilayer dielectric and bilayer PR lift-off have an optimum uniformity of process. ► The mechanism of enhancing performance was verified by a physics-based simulation.
