This project is aimed at the study of low-dimensional correlated electron systems using the two conceptually simple but highly effective techniques angle-resolved photoemission spectroscopy (ARPES) and scanning tunnelling microsopy/spectroscopy (STM/STS). Experiments focus on measuring the experimental band structure and Fermi surface as well as the sample topography and local electron density of states in artificial, ordered one- and two-dimensional structures on metallic and semiconducting surfaces. The goal is to understand the interactions of the electrons in their environment within the low-dimensional system as well as beyond its confinement. From the experimental point of view, the project will provide the opportunity to refine the knowledge in ARPES as wll as to expand the experience in local scanning probe microscopy and spectroscopy.

本计画旨在利用角分辨光电子能谱（ARPES）与扫描隧道显微镜/光谱（STM/STS）这两种概念简单但却非常有效的技术来研究低维关联电子系统。实验的重点是测量实验的能带结构和费米面以及样品的形貌和局部电子态密度在人工，有序的一维和二维结构的金属和半导体表面。我们的目标是了解电子在低维系统内以及超出其限制的环境中的相互作用。从实验的角度来看，该项目将提供一个机会，以完善的知识，在ARPES以及扩展本地扫描探针显微镜和光谱学的经验。
