Abstract
Thin-film transistors (TFTs) are a key technology in large-area electronics and can be manufactured uniformly over large areas—on glass or flexible substrates—at lower processing temperatures and costs than complementary metal–oxide–semiconductor (CMOS)-based transistors. The transistors are used in established applications such as flat-panel displays and X-ray detectors, and are of potential use in a range of emerging applications. Here we discuss the development of TFTs for large-area electronics. We explore the use of TFTs—which can be based on hydrogenated amorphous silicon, low-temperature polycrystalline silicon, amorphous oxide semiconductors and organic semiconductors—in displays and sensors, as well as digital circuits and memory. We also consider their potential use in emerging applications such as neuromorphic computing.
