Core Viewpoint - The research team from the Institute of Physics, Chinese Academy of Sciences, has discovered a one-dimensional charged domain wall in ferroelectric materials with a thickness and width approximately one hundred thousandth of a human hair, providing a scientific basis for developing devices with extreme storage density [1] Group 1: Research Findings - The discovery challenges the traditional belief that domain walls in three-dimensional crystals must be two-dimensional surfaces [1] - The potential applications of ferroelectric materials are significant in fields such as information storage, sensing, and artificial intelligence [1] Group 2: Storage Density Potential - Utilizing one-dimensional charged domain walls for information storage could increase storage density by several hundred times, theoretically reaching about 20TB per square centimeter [1] - This storage capacity is equivalent to storing 10,000 high-definition movies or 200,000 high-definition short videos on a device the size of a postage stamp [1]
