Carbon nanotube field effect transistor (CNFET) is more energy-saving than silicon field effect transistor and can be used to construct new three-dimensional microprocessor. But until now, most of them exist in academic laboratories, and only a small amount of production is used for academic experiments.

China's traditional chip industry based on silicon-based CMOS technology has always been in a relatively backward situation of being "stuck" by the West. So in the field of new materials integrated circuits other than silicon, what is China's winning geometry and layout?

There are many choices of post-Moore technology, such as GAA promoted by Samsung and negative capacitance transistor promoted by Professor Hu Zhengming, the inventor of FinFET, are all representatives of it, carbon nanotubes are the school that another group of people insist on.

Carbon nanotubes are mainly composed of hexagonal carbon atoms to form several to dozens of coaxial circular tubes. Maintain a fixed distance between layers, about 0.34nm, with a diameter of 2~20 nm.

Nowadays, carbon nano-tube powder, carbon nano-tube conductive paste, graphene composite conductive paste, carbon nano-tube conductive masterbatch and so on are the main products of Tenet Technology.

Researchers at the University of Eastern Finland have developed a mixed material made of mesopores Silicon (PSi) particles and carbon nanotubes (CNT). Researchers believe that this kind of composite material can be realized only when the positive PSi and CNT are chemically combined, so as not to prevent the diffusion of lithium ions to silicon.

Scientists from the U.S. Department of Energy's Pacific Northwest National Laboratory (PNNL) have found a new method to take advantage of this kind of Energy storage component with good prospects but many problems.

A few days ago, researchers from Washington State University (WSU) and Pacific Northwest National Laboratory (PNNL) developed a sodium ion battery, the energy storage capability of this kind of battery is equivalent to the chemical performance of some commercial lithium ion batteries, which makes it possible to develop a possible and feasible battery technology by using rich and cheap materials.

Jiang Hong, a professor of China University of Science and Technology, cooperated with Yu Hanqing, through coupling rapid pyrolysis, atmospheric distillation and chemical vapor deposition technology, high calorific value and stable solid phase biological coal (bio-coal) and high performance carbon nanomaterials (less-layer graphene and carbon nanotubes) have been successfully prepared respectively, it provides important technical support for the commercial application of waste biomass pyrolysis technology.

With the progress and development of high-end technology, the demand for field effect transistors (FETs) with high density, high performance and high energy efficiency in industrial production is becoming more and more urgent.

With the intensification of market competition, a large number of second-and third-tier lithium battery material enterprises are facing pressure and challenges such as sharp shrink of revenue orders, sharp decline of gross profit and net profit of products, etc. How to choose products, markets, customers become an important topic for their continued survival.
