摘要: Angle-resolved photoemission spectroscopy (ARPES) has become a cornerstone technique for elucidating the electronic structures of emergent quantum materials. Among these, kagome materials - distinguished by their two-dimensional lattice of corner-sharing triangles - provide a fertile ground for investigating exotic quantum phenomena, driven by geometric frustration, electronic correlation, and topology. In this review, we present an overview of recent ARPES studies on transition-metal kagome materials. We first outline the fundamental features of their electronic structures, including van Hove singularities, Dirac points, and flat bands, and discuss the novel quantum states that arise from many-body interactions within the kagome lattice. We then highlight key ARPES investigations into these unique electronic structures, detailing their manifestation and associated quantum states in representative kagome materials. Finally, we offer a forward-looking perspective on the potential of ARPES to uncover new quantum phenomena and its broader implications for the study of underlying physics in kagome materials.
