The electronic structure of non-magnetic low-dimensional materials can acquire a spin structure due to the breaking of the inversion symmetry at the surface or interface. This so-called Rashba effect is a prime candidate for the manipulation of the electron spin without using any magnetic fields. This is crucial for the emerging field of spintronics, where the spin of the electron instead of its charge is used to transport or store information. Spin and angle resolved photoemission is currently one of the main experimental methods to measure the spin resolved electronic structure, which contains all the relevant information for spintronics. In this review, the technique of spin and angle resolved photoemission will be explained and recent results on low-dimensional non-magnetic structures will be discussed.
由于表面或界面处的空间反演对称性破缺，非磁性低维材料的电子结构可以获得自旋结构。这种所谓的 Rashba 效应是在不使用任何磁场的情况下操纵电子自旋的主要候选对象。这对于新兴的自旋电子学领域至关重要，在该领域中，电子的自旋而非电荷被用于传输或存储信息。自旋和角分辨光电子能谱是目前测量自旋分辨电子结构的主要实验方法之一，它包含了自旋电子学的所有相关信息。在这篇综述中，将解释自旋和角分辨光电子能谱技术，并讨论低维非磁性结构的最新研究成果。
