Spin-resolved electonic properties of strongly correlated one-dimensional systems

我们将研究准一维(准一维)纳米线甚至单原子链在梯形半导体和低指数金属表面上的自组织过程所形成的局域电子和磁性。研究将通过自旋极化扫描隧道显微镜和衍生的原子尺度的光谱技术进行，能量分辨率远低于1毫电子伏特(MEV)。这些方法非常适合于验证和研究理论上预言的许多强自旋轨道耦合的一维系统的自旋有序现象，并提供在倒易和真实空间中的态密度效应和散射现象的途径。特别是，我们将仔细审查缺陷和有限尺寸效应的影响，这些缺陷和有限尺寸效应要么是由不完美的样品结构引起的，要么是由故意操纵原子尺度引起的。

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
