We demonstrate doping-free and adaptive inverter to verify that the single ambipolar SWCNT transistors can be utilized both p- and n-type. Furthermore, we fabricate an adaptive logic circuit that can reveal multifunctions such as NOR and NAND gate using four ambipolar transistors. This new approach is innovative in several aspects, for instance, in improving integration density, simplicity without intentional doping, and its multifunctionality and ensures multidisciplinary interests in materials, physics, mechanics, and electronics areas.
