Raw data underlying the publication: Tunability of Topological Edge States in Germanene at Room Temperature

This dataset contains the raw data underlying the figures in the publication: Tunability of Topological Edge States in Germanene at Room Temperature. The dataset contains STS and STM data obtained using an Omicron Low-Temperature Scanning Tunneling Microscope (LT-STM) at 77K and 300K. In this publication, we show that the topological edge states of germanene persist at room temperature using STS and STM measurements. Additionally, we demonstrate that, even at room temperature, applying an external electric field switches the topological states of germanene off. These findings indicate that germanene's topological properties can be maintained and controlled at room temperature, making it a promising material for low-energy electronic applications.

本数据集包含发表论文《室温下锗烯拓扑边缘态的可调谐性》（Tunability of Topological Edge States in Germanene at Room Temperature）的配图所依托的全部原始实验数据。数据集涵盖使用Omicron低温扫描隧道显微镜（Low-Temperature Scanning Tunneling Microscope, LT-STM）在77K与300K温度下采集得到的扫描隧道谱（Scanning Tunneling Spectroscopy, STS）与扫描隧道显微镜（Scanning Tunneling Microscope, STM）测试数据。本研究通过STS与STM测量证实，锗烯的拓扑边缘态在室温下依然稳定存在。此外，研究还证明，即便在室温环境中，施加外部电场即可关闭锗烯的拓扑态。上述研究结果表明，锗烯的拓扑特性可在室温下得以维持与精准调控，使其成为低能耗电子应用领域极具潜力的候选材料。
