Single-Walled Carbon Nanotube Thin Film for Flexible from freeamfva's blog
Metal–halide perovskites have recently shown tremendous progress in flexible photodetector applications owing to their great optical and electronic properties. However, apart from charge generating material, the high performance device requires a reasonable choice of electrodes for efficient carrier management as well. For example, the widespread use of gold and silver electrodes often results in perovskite device degradation while being expensive. Here, low-cost and chemically inert single-walled carbon nanotube (SWCNT) thin films are employed as electrodes to create highly responsive and flexible photodetector based on cesium lead tribromide (CsPbBr3) microcrystals. Direct growth of the perovskite on SWCNT forms excellent contact between the components leading to the state-of-the-art responsivity for flexible perovskite photodetectors 1321 A W−1 at 5 V and under illumination intensity 1 mW cm−2 at 505 nm wavelength. The advanced properties of SWCNT films realized on a flexible substrate allow for robust operation over 104 cycles of device bending along with all parameters stability at ambient conditions for at least 1.5 months. The proposed design reveals the potential of SWCNT thin film electrodes for high performance perovskite flexible devices.Get more news about Carbon Nanotube Thin Film,you can vist our website!
Printing technologies have attracted significant attention owing to their potential use in the low-cost manufacturing of custom or large-area flexible electronics. Among the many printable electronic materials that have been explored, semiconducting carbon nanotubes (CNTs) have shown increasing promise based on their exceptional electrical and mechanical properties, relative stability in air, and compatibility with several printing techniques to form semiconducting thin films.
These attractive attributes make printed CNT thin films promising for applications including, but not limited to, sensors and display backplanes – at the heart of which is electronics’ most versatile device: the transistor. In this review, we present a summary of recent advancements in the field of printed carbon nanotube thin-film transistors (CNT-TFTs). In addition to an introduction of different printing techniques, together with their strengths and limitations, we discuss key aspects of ink/material selection and processing of various device components, including the CNT channels, contacts, and gate insulators. It is clear that printed CNT-TFTs are rapidly advancing, but there remain challenges, which are discussed along with current techniques to resolve them and future developments towards practical applications from these devices. There has been interest in low-cost, printable transistors for many years and the CNT-TFTs show great promise for delivering, but will not become a reality without further research advancement.
