Organic heterojunction transistors for mechanically flexible multivalued logic circuits

Organic multivalued logic circuits (OMVLs) have drawn tremendous attention due to their high data processability and simple fabrication techniques. However, OMVLs have so far been achieved only on rigid silicon substrates, and this limits their potential for broader applications. In this study, we develop an organic ternary inverter on plastic substrates. The inverters showed well-balanced ternary logic states with high voltage gain and low power consumption. Importantly, the devices exhibited stable operation even after 100 bending cycles, demonstrating high flexibility and reliability. This device has high potential to attain mechanical flexibility and data handling capability at the same time.
