On March 18th, Sergey Savrasov, a physics professor at the University of California, Davis, published a paper in Nature Materials. Researchers from China and the University of California at Davis have made a very thin layer of niobium-arsenic with high conductivity, which is called Weyl semimetal.
Sergey Savrasov said that the conductivity of this material at room temperature is about three times that of copper.
Even more amazing is that the surface of the material has good conductivity to electricity. It is also very difficult to absorb impurities due to the topological effect, and it is not easy to produce chemical changes. This means that the material will not reduce the conductivity with the use of longer time. It has extremely broad application prospects in the semiconductor industry.
And because there are few impurities, so electrons will not rebound and scatter in the impurities, so the heat dissipated by the current in the circuit will also be greatly reduced, which provides the basic conditions for manufacturing larger integrated circuits.
The chip engineers don't have to worry about the process of a few nanometers, but this technology has just come out, and it is still far away from the actual application. You need to wait patiently.
LED headlamps have become increasingly popular in recent years, thanks to their convenience, durability, and energy efficiency. They are the perfect solution for anyone who needs an effective lighting tool for their outdoor activities or work, such as hiking, camping, fishing, or construction. With advanced features such as rechargeable batteries, adjustable brightness levels, and lightweight design, LED headlamps provide users with a convenient, hands-free lighting experience. Brands like Streamlight Headlamp have established themselves as industry leaders in producing high-quality head torch lights that are reliable and long-lasting. Whether you're a professional outdoorsman or just need a reliable light for your DIY projects, an LED headlight is a versatile tool that you can count on.
