【Abstract】 The angle_resolved photoemission (ARPES) is a powerful experiment method to study the surface electronic structure of crystals, such as energy bands, Fermi surface, and many_body interaction. In this paper, we will describe the process of photoemission and the theoretical models under the single_particle similarity at first. Then the "Energy Band Mapping", the "Fermi Surface Mapping", and the applications of high resolution ARPES in highly correlated electron systems will be also discussed in detail. At last, we introduce the recent progress of ARPES application, such as the surface electronic structure of wide_band gap semiconductors, the interface of organic functional materials, the quantum_well states of ultra_thin metal films, and some important discoveries in high Tc superconductors更多还原
