247. 统一理论揭示超导材料新发现

from 知为谁 · host 知为谁

宾夕法尼亚州立大学的研究人员正在开发一种新方法来识别超导材料,这些材料允许电流在没有能量损失的情况下流动。这项工作可能导致在更高温度下运行的新型超导体,从而彻底改变能源传输和电子设备。传统上,Bardeen-Cooper-Schrieffer (BCS) 理论解释了低温超导体,但对于高温超导体无效。由 Zi-Kui Liu 教授领导的团队将 BCS 理论与密度泛函理论 (DFT) 和熵理论相结合,创建了一个可以预测超导行为和转变温度的统一框架。这种新方法已经成功地预测了已知超导体和以前未被识别为超导体的材料中的超导迹象,例如铜、银和金。该团队的最终目标是发现甚至可能在室温下运行的超导体,这将对现代技术和能源系统产生深远影响。内容来源: https://www.psu.edu/news/materials-research-institute/story/unified-theory-may-reveal-more-superconducting-materials
