New conductive materials come out

At present, the main conductive material is copper. As the size of computing devices becomes smaller and smaller, when copper becomes very thin and enters a two-dimensional scale, the resistance becomes larger, the conductivity becomes worse quickly, and the power consumption increases significantly. An important bottleneck restricting the further development of integrated circuit technologies such as chips.

The team of professor Xiu Faxian from the Department of Physics of Fudan University used three elements of niobium chloride, arsenic, and hydrogen to prepare this niobium arsenide nanoribbon. This material has a surface state that allows electrons to pass on it quickly. The rapid passage of electrons reduces energy consumption.

And this paper has also been praised by reviewers of natural materials, saying that this method for preparing niobium arsenide nanoribbons is very interesting and very innovative, which is currently lacking and needed in the field of materials. In the electronics industry , conductive materials are the basis of this industry, and are widely used in the industry. However, with the advancement of the information era, the difficulties of tens of millions of transistors in chips in interconnecting wires have also increased, so The development of conductive materials is also more important. At this stage, the conductive material mainly uses copper, and this material has been used in large-scale interconnection wires.

However, as the size of the equipment becomes smaller and smaller, the information transmission requirements have increased exponentially. In the face of this development model, copper can only become thinner and thinner, and various problems arise. The larger the resistance, the worse the conductivity. Especially after the conductive material enters the two-dimensional system, the development of the conductive material is the development of the chip. Only through the breakthrough of the conductive material will there be better development of the subsequent chip.

But this new molding material changed this situation, various types of conductor element efficiency can be improved to a great extent and reduce losses. Xiu Faxian also said that the main function of this niobium arsenide nanoribbon material is to solve the heat generation of conductive devices, because the transistor itself will heat up, plus the heat generated by the electrical wires, which is our mobile phone and computer The reason why it will heat after use.

The result of the Xiufaxian team this time is a subversive existence. According to reports, they used a variety of elements to create a green channel-like existence, allowing electrons to pass quickly at a low dimensional scale and reduce energy consumption. . Unlike superconducting materials, which can only be quoted in ultra-low temperature environments such as minus tens of degrees, new materials are also effective at room temperature, which also provides a viable idea for materials science to find high-performance conductors. Reduction.

And this new type of material can start with infrared radiation, making the J-20 more stealthy in the future.
