Abstract
We report clocked sequential complementary circuits that operate at 5 V in which the active semiconductors are deposited by inkjet printing. The p-channel thin-film transistors (TFTs) employ a network of predominantly semiconducting (>98%) single-walled carbon nanotubes and the n-channel TFTs employ amorphous zinc tin oxide formed from a printed precursor solution. The gate insulator material in both cases is zirconium oxide, deposited from solution. Edge triggered D flip-flops operate at clock speeds of 2.5 kHz. Our results suggest that this materials combination is promising for use in printed electronics.
