Chinese scientists have developed a new type of ultra-high conductive material. Conductivity is 1,000 times that of graphene.

Today (March 19), the world's top journal in the field of materials, "Nature·Materials", published the latest research paper of Fudan University's Xiu Faxian team, "Ultra-high conductivity in the semi-metal arsenide bismuth nanobelts", prepared In the two-dimensional system, there is a foreign semi-metal material known as the highest conductivity, a arsenide arsenide nanobelt.
Conductive materials are the foundation of the electronics industry, and now the most important material is copper, which has been used on a large scale for interconnecting wires of transistors. In the information age, the size of computers and smart devices is getting smaller and smaller, and the amount of signal transmission is exploding. The "transport pressure" of tens of millions of thin wire interconnected wires in the chip is increasing. When the copper becomes very thin and enters the two-dimensional scale, the electric resistance becomes large, the electrical conductivity rapidly deteriorates, and the power consumption is greatly increased. This is also an important bottleneck restricting the further development of integrated circuit technologies such as chips. The new arsenide arsenide nanobelt material developed by Xiu Faxian team has a conductivity of one hundred times that of copper film and one thousand times that of graphene.
Professor Fu Faxian, a professor of physics at Fudan University: We used cesium chloride and used arsenic and hydrogen to put them together for chemical reaction to prepare the arsenic arsenide nanobelt. A surface state that allows electrons to pass quickly on it. It can be said that we have created a green channel, so that at low dimensional scales, electrons can pass quickly and reduce energy consumption.
At the same time, the superconducting material can only be applied at ultra-low temperature of tens of degrees below zero. The high conductivity mechanism of the new material arsenide arsenide is effective even at room temperature. This discovery also provides a feasible idea for material science to find high-performance conductors, and has great value in reducing the energy consumption of electronic devices.
Professor Fu Faxian, a professor of physics at Fudan University: There are two reasons why our mobile phones are heated and computerized. The heat generated by the transistors themselves and the current flowing through these (interconnected) wires are hot. So we have to solve the problem now. It is the heat of the wire, and our material can be used for this purpose.
