We will study the local electronic and magnetic properties of quasi-one-dimensional (quasi- 1D) nanowires or even single-atomic chains of heavy elements that form as a result of self-organization processes on terraced semiconductor and low-index metal surfaces. Investigations will be performed by spin-polarized scanning tunneling microscopy and derived spectroscopic techniques at the atomic scale and with an energy resolution well below one millielectronvolt (meV). These methods are ideally suited to verify and investigate the spin-order phenomena which were theoretically predicted for numerous of these strongly spin-orbit coupled one dimensional systems, and give access to density of states effects and scattering phenomena in both, reciprocal and real space. In particular, we will scrutinize the impact of defects and finite-size effects caused by either an imperfect sample structure or intentionally induced by deliberate manipulation on the atomic scale

我们将研究准一维（准1D）纳米线的局部电子和磁性，甚至是重元素的单原子链，这些重元素是由于阶梯状半导体和低指数金属表面的自组织过程而形成的。调查将进行自旋极化扫描隧道显微镜和衍生的光谱技术在原子尺度和能量分辨率远低于1毫电子伏（meV）。这些方法非常适合于验证和调查的自旋序现象，这是理论上预测的许多这些强自旋轨道耦合的一维系统，并获得态密度效应和散射现象在这两个，倒易和真实的空间。特别是，我们将仔细研究缺陷和有限尺寸效应的影响，无论是由不完美的样品结构或故意诱导的故意操纵原子尺度上
