The hottest new carbon nanotube thin film transist

Recently, scientists have developed a new type of carbon nanotube that optimizes the balance between metallicity and semiconductivity, and used this nanotube to create a long-term mechanism to promote energy conservation and the development of new energy vehicles. Thin film transistor (TFT) has been developed, which is expected to develop high-performance, transparent and flexible devices such as e-books and electronic labels in the future

from January 1, he participated in a seminar sponsored by the company. Sun Dongming, a scientist from the original name of the University of Guya, and his colleagues, as well as scientists from the University of Alto in Finland, introduced the research on using this new carbon nanotube to manufacture thin-film transistors and flexible integrated circuits in the latest issue of Nature Nanotechnology

the electronic properties of carbon nanotubes can be divided into metallic and semiconductor properties, and the carbon nanotubes of these two properties "stick" to each other into rope or bundle shape. At this time, the metallicity is stronger than the semiconductivity, and only semiconductor nanotubes can be used as transistors, which greatly reduces the use of carbon nanotubes. Although metallicity can increase the motion ability of transistor loaders, it can also reduce the switching frequency of transistors

in the latest research, scientists have developed a new way to manufacture carbon nanotubes, which optimizes the balance between the metallicity and semiconductivity of nanotubes. The new nanotube complex contains straight, relatively long (10 microns) nanotubes (30% of which are metal), and the Y-shaped interfaces between the nanotubes in the new complex are more than the X-shaped interfaces, and their resistance is also lower

scientists use this new nanotube complex, but because of its function, compared with Dan 1, they have manufactured thin-film transistors. Compared with the previous nano transistors, the new transistors have high carrier mobility and switching frequency. The researchers said that the high exercise ability is mainly due to the unique shape of nanotube complexes; High switching frequency is due to the fact that the density of metal nanotubes can be controlled by the construction process, so that the density is lower

scientists have also produced an integrated circuit that can process sequential logic, which is the first sequential logic integrated circuit based on carbon nanotubes so far. In this circuit, the output value depends not only on the current input value, but also on the historical input value, which makes it have the ability of storage or memory

the co-author of the study and professor of Nagoya University, Yu Ono, said that by detecting the phase transition temperature and thermal expansion coefficient of the film through reflected light power, making the manufacturing process large-scale and using improved printing technology, scientists can use these nanotube based thin-film transistors to produce cheap flexible electronic products, such as smart and electronic paper. It is expected to realize commercial production within 5 years
