Data underlying the publication: Realization of a one-dimensional topological insulator in ultrathin germanene nanoribbons

This is the dataset used in the publication: Realization of a one-dimensional topological insulator in ultrathin germanene nanoribbons. In this publication, we present a transition from a 2D topological insulator with 1D edge states towards a 1D topological insulator with 0D end states in ultrathin germanene nanoribbons. We use STM, STS, uLEED and theory to explain our findings. The dataset presented here contains STS and STM data obtained using an Omicron Low-Temperature Scanning Tunneling Microscope (LT-STM) at 77K.

本数据集来自发表论文《超薄锗烯纳米带中一维拓扑绝缘体的实现》。在该研究中，我们报道了超薄锗烯纳米带从具备一维边缘态的二维拓扑绝缘体，向具备零维末端态的一维拓扑绝缘体的拓扑相变过程。我们采用扫描隧道显微镜（STM，Scanning Tunneling Microscope）、扫描隧道谱（STS，Scanning Tunneling Spectroscopy）、超低能电子衍射（uLEED，ultra-low-energy electron diffraction）以及理论计算对研究发现进行了解释。本数据集包含了在77K温度下，使用欧米克朗（Omicron）低温扫描隧道显微镜（LT-STM，Low-Temperature Scanning Tunneling Microscope）采集得到的STS与STM实验数据。
