One-dimensional (1D) zigzag tellurium (Te) wires on an alloyed Cu2Sb (111) surface are produced and characterized by combining molecular beam epitaxy and high-resolution scanning tunneling microscopy, respectively. These 1D Te wires with zigzag shapes exhibit a uniform width and well-defined periodicity grown in registry on a Cu2Sb (111) substrate. Density functional theory (DFT) calculations revealed a remarkable bandgap of 0.3 eV induced by spin–orbit coupling. Interestingly, the resulting Te wires became metallic on the substrate, as confirmed by scanning tunneling spectroscopy and DFT. The present study provides a platform for constructing periodic atomic wires on alloyed surfaces, which may be extended further to integrate them into circuits.

Cu2Sb表面合金单碲原子线的外延生长

通过分别结合分子束外延和高分辨率扫描隧道显微镜，在合金化 Cu2Sb (111) 表面上产生和表征一维 (1D) 之字形碲 (Te) 线。这些具有锯齿形的 1D Te 线在 Cu2Sb (111) 衬底上以注册方式生长，表现出均匀的宽度和明确的周期性。密度泛函理论 (DFT) 计算揭示了由自旋轨道耦合引起的 0.3 eV 的显着带隙。有趣的是，正如扫描隧道光谱和 DFT 所证实的那样，所得的 Te 线在基板上变成了金属。本研究为在合金表面上构建周期性原子线提供了一个平台，可以进一步扩展以将它们集成到电路中。
