论文摘要
samarium hexaboride在简单的立方结构（221，PM-3M）中结晶，但其特性远非直接。 SMB6最初被归类为从其吸引人的中间价基态出生的围绕中的绝缘子，最近被预测是一种密切相关的拓扑绝缘体。随后的表面状态实验发现恢复了对SMB6的兴趣，我们的目的是审查该材料的实验记录的广泛和许多方面。我们将讨论SMB6的表面和大量特性，重点是晶体生长和样品制备的作用。我们还将重点介绍其余的谜团，并在该领域开放问题。
Samarium hexaboride crystallizes in a simple cubic structure (space group #221, Pm-3m), but its properties are far from being straightforward. Initially classified as a Kondo insulator born out of its intriguing intermediate valence ground state, SmB6 has been recently predicted to be a strongly correlated topological insulator. The subsequent experimental discovery of surface states has revived the interest in SmB6, and our purpose here is to review the extensive and in many aspects perplexing experimental record of this material. We will discuss both surface and bulk properties of SmB6 with an emphasis on the role of crystal growth and sample preparation. We will also highlight the remaining mysteries and open questions in the field.
