- Abstract
- ZnO-nanowire-based logic circuits were constructed by the vertical integration of multilayered field-effect transistors (FETs) on plastic substrates. ZnO nanowires with an average diameter of similar to 100 nm were synthesized by thermal chemical. vapor deposition for use as the channel material in FETs. The ZnO-based FETs exhibited a high I-ON/I-OFF of > 10(6), with the characteristic of n-type depletion modes. For vertically integrated logic circuits, three multilayer FETs were sequentially prepared. The stacked FETs were connected in series via electrodes, and C-PVPs were used for the layer-isolation material. The NOT and NAND gates exhibited large logic-swing values of similar to 93%. These results demonstrate the feasibility of three dimensional flexible logic circuits.
