Chinese Scientists Achieve Breakthrough in High-Temperature Superconductivity
Scientists at Southern University of Science and Technology (Sustech) in China have observed high-temperature superconductivity in a thin film of nickel oxide crystals, achieving resistance-free electricity conduction at a relatively high temperature of 45 Kelvin (-228°C) without high pressure. Published in Nature, this research offers new hope for understanding the mechanism of high-temperature superconductivity and designing room-temperature superconductors. The discovery promises to make technologies like magnetic resonance imaging significantly cheaper and more efficient. While the critical temperature of nickel-based superconductors still needs improvement compared to copper-based ones, the team is actively exploring ways to optimize the material's growth and composition to further raise its critical temperature.
