论文摘要
我们将STM对两种六边形化合物，SMB $ _6 $和EUB $ _6 $进行比较，以提供全面的表面结构属性。后者对于通过表面敏感工具以SMB $ _6 $研究表面状态的性质非常重要。除了经常遇到的{\ IT原位}的原子粗糙的表面地形外，低温裂解样品，不同的重建以及B终止，更少的，更罕见的稀有地点终止区域。在两个六边形上都观察到所有不同的表面地形，可以提出表面终止的可靠分配。
We compare STM investigations on two hexaboride compounds, SmB$_6$ and EuB$_6$, in an effort to provide a comprehensive picture of their surface structural properties. The latter is of particular importance for studying the nature of the surface states in SmB$_6$ by surface-sensitive tools. Beyond the often encountered atomically rough surface topographies of {\it in situ}, low-temperature cleaved samples, differently reconstructed as well as B-terminated and, more rarely, rare-earth terminated areas could be found. With all the different surface topographies observed on both hexaborides, a reliable assignment of the surface terminations can be brought forward.
