Our country's scientists have made another breakthrough in the field of high-temperature superconductors based on nickel under atmospheric pressure.

Chinese scientists announced on the 9th that they have made another breakthrough in the field of high-temperature superconductors based on nickel under normal pressure, creating a new type of nickel-based oxide superconductor through atomic-level precision engineering. The team led by Xue Qikun and Chen Zhuoyu from the National Key Laboratory of Quantum Functional Materials at the Southern University of Science and Technology, as well as the Physics Department and the Quantum Science Center of the Guangdong-Hong Kong-Macao Greater Bay Area, collaborated with the team led by Shen Dawei from the University of Science and Technology of China. On the evening of April 8, they published their latest research results in the international academic journal "Nature", creating two new types of high-temperature superconductors under normal pressure - single layer-double layer superstructures and double layer-triple layer superstructures under extreme oxidation conditions by artificially designing atomic stacking sequences. They also identified the electronic band structure corresponding to the superconducting state through angle-resolved photoemission spectroscopy, providing key experimental evidence for unraveling the mechanism of high-temperature superconductivity. These achievements represent significant progress made by the same joint research team at the end of 2024 in discovering and establishing the electrical properties of high-temperature superconductors based on nickel under normal pressure. From achieving high-temperature superconductivity under normal pressure, to improving superconducting performance, to artificially creating new superconducting materials and revealing their electronic structure origins, this series of breakthroughs demonstrates China's continuous and independent innovative capabilities in the cutting-edge research field of high-temperature superconductors.
