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
