论文摘要
六边形材料类中的化合物表现出各种有趣的物理现象，包括极性形成和四极阶。特别是，SMB $ _6 $最近引起了人们的注意，因为它被认为是典型的拓扑杂种绝缘子。然而，支持这一概念的证据在实验上很困难且有争议，部分原因是所需的温度和能量解决方案。在这里，一个强大的工具是扫描隧道显微镜（STM），其独特的能力可以提供与一颗绿色功能直接相关的局部微观信息。然而，六边形上的STM面临着自己的一系列挑战。本文试图回顾STM对Hexaborides的调查的进展，重点是SMB $ _6 $及其有趣的属性。
Compounds within the hexaboride class of materials exhibit a wide variety of interesting physical phenomena, including polaron formation and quadrupolar order. In particular, SmB$_6$ has recently drawn attention as it is considered a prototypical topological Kondo insulator. Evidence in favor of this concept, however, has proven experimentally difficult and controversial, partly because of the required temperatures and energy resolution. Here, a powerful tool is Scanning Tunneling Microscopy (STM) with its unique ability to give local, microscopic information that directly relates to the one-particle Green's function. Yet, STM on hexaborides is met with its own set of challenges. This article attempts to review the progress in STM investigations on hexaborides, with emphasis on SmB$_6$ and its intriguing properties.
