论文摘要
我们回顾了称为极性金属的材料类别，其中极性和金属性在同一阶段共存。虽然极地金属的概念首先是在50年前首次提到的，但实际上，它们的实际认识已被证明具有挑战性，因为金属性所需的巡回载体倾向于筛选任何极化。在过去的十年中，取得了巨大的进步，具有许多用于结合极性和金属性的机制，并且第一个例子lioso3和wte2是通过实验确定的。极性金属样品的可用性为极性金属研究开辟了一个新的范式，对拓扑，铁电性，磁电性，旋转三节药和超导性的影响具有影响。在这里，我们回顾了为设计和设计极地金属而开发的原理和技术，并描述了它们的一些有趣的属性，重点关注未来工作的最有希望的方向。
We review the class of materials known as polar metals, in which polarity and metallicity coexist in the same phase. While the notion of polar metals was first invoked more than 50 years ago, their practical realization has proved challenging, since the itinerant carriers required for metallicity tend to screen any polarization. Huge progress has been made in the last decade, with many mechanisms for combining polarity and metallicity proposed, and the first examples, LiOsO3 and WTe2, identified experimentally. The availability of polar metallic samples has opened a new paradigm in polar metal research, with implications in the fields of topology, ferroelectricity, magnetoelectricity, spintronics, and superconductivity. Here, we review the principles and techniques that have been developed to design and engineer polar metals and describe some of their interesting properties, with a focus on the most promising directions for future work.
