Si-nanowire (NW)-array-based NOT-logic circuits were constructed on plastic substrates. The Si-NW arrays were fabricated on a Si wafer through top-down methods, including conventional photolithography and crystallographic wet etching, and transferred onto the plastic substrates. Two field-effect transistors were fabricated on a single Si-NW array composed of five nanowires aligned in parallel and connected in series to form NOT-logic circuits. The excellent flexibility of the fabricated device was confirmed by bending-cycling tests. The voltage-transfer curve of the NOT-logic circuits showed an inverting operation with a logic swing of ~92% and voltage gain of ~2.5.
