Organic Complementary Inverters Based on Step-Edge Vertical Channel Organic Field-Effect Transistors

An organic complementary inverter which consists of a p-channel pentacene step-edge vertical channel organic field-effect transistor (SVC-OFET) and an n-channel hexadecafluorophthalocyanine (F 16 CuPc) SVC-OFET has been demonstrated. The two short-channel SVC-OFETs have been fabricated on the two st...

Summary:An organic complementary inverter which consists of a p-channel pentacene step-edge vertical channel organic field-effect transistor (SVC-OFET) and an n-channel hexadecafluorophthalocyanine (F 16 CuPc) SVC-OFET has been demonstrated. The two short-channel SVC-OFETs have been fabricated on the two steep side walls of a single gate line using a self-aligning technique. Such a structure significantly simplifies the layout and wiring of the inverter circuit. The inverter exhibited the same input and output swing ranges as the supply voltage, a logic threshold voltage very close to half of the supply voltage and a gain larger than 3.
