【新华社】极限密度！我国新成果有望让器件“存得更多 占得更少”

Core Viewpoint - The research team from the Chinese Academy of Sciences has discovered a one-dimensional charged domain wall in ferroelectric materials, which significantly enhances storage density, providing a scientific basis for developing devices with extreme density [1] Group 1: Research Findings - The thickness and width of the discovered domain wall are approximately one hundred thousandth of a human hair, challenging the traditional belief that domain walls in three-dimensional crystals must be two-dimensional surfaces [1] - The research results have been published in the international academic journal "Science" on January 23 [1] Group 2: Applications and Potential - Ferroelectric materials have immense potential in information storage, sensing, and artificial intelligence [1] - Utilizing one-dimensional charged domain walls for information storage could increase storage density by several hundred times, theoretically reaching about 20TB per square centimeter, equivalent to storing 10,000 HD movies or 200,000 HD short videos on a device the size of a postage stamp [1]
