  • Title: Air-stable ambipolar field-effect transistors and complementary logic circuits from solution-processed n/p polymer heterojunctions.
    Author: Kim FS, Ahmed E, Subramaniyan S, Jenekhe SA.
    Journal: ACS Appl Mater Interfaces; 2010 Nov; 2(11):2974-7. PubMed ID: 20945932.
    Abstract:
    We demonstrate the use of n/p polymer/polymer heterojunctions deposited by sequential solution processing to fabricate ambipolar field-effect transistors and complementary logic circuits. Electron and hole mobilities in the transistors were ∼0.001-0.01 cm(2)/(V s) in air without encapsulation. Complementary circuits integrating multiple ambipolar transistors into NOT, NAND, and NOR gates were fabricated and shown to exhibit sharp signal switching with a high voltage gain.
