论文摘要
具有光学吸收损失的假设金属与透明绝缘子的光损失（如果发现）可能会彻底改变光电子。我们在超过100,000个条目的数据库中的所有已知无机材料中进行了第一次高通量搜索，以对无损金属进行高通量搜索。确定了381个候选人 - 具有良好的部分填充频段 - 并通过定义功绩的数字并分类其真实空间导电连通性来分析。现有的实验证据表明，大多数候选者是绝缘而不是进行进行的，这是由于当前密度功能理论在预测不稳定的窄带金属方面的限制，这些金属不稳定，而这些金属不稳定磁性，结构变形或电子电子相互作用。我们提出了未来的研究方向，包括导电氧化物，插入分层材料以及在高压下将这些假金属候选者压缩成最终的无损金属。
Hypothetical metals having optical absorption losses as low as those of the transparent insulators, if found, could revolutionize optoelectronics. We perform the first high-throughput search for lossless metals among all known inorganic materials in the databases of over 100,000 entries. The 381 candidates are identified -- having well-isolated partially-filled bands -- and are analyzed by defining the figures of merit and classifying their real-space conductive connectivity. The existing experimental evidence of most candidates being insulating, instead of conducting, is due to the limitation of current density functional theory in predicting narrow-band metals that are unstable against magnetism, structural distortion, or electron-electron interactions. We propose future research directions including conductive oxides, intercalating layered materials, and compressing these false-metal candidates under high pressures into eventual lossless metals.
