最近发现的层状kagome超导体sav3sb5 （A= K, Rb, Cs）引起了极大的关注，因为它们表现出了超导性，电荷密度波（CDW）秩序和非寻常带拓扑结构的有趣组合。因此，这些kagome系统作为一个特殊的量子平台，用于研究电子相关效应、几何挫折和拓扑电子结构之间复杂的相互作用。全面了解潜在的电子结构对于揭示CDW秩序的性质和起源以及确定kagome超导体中的电子对对称性至关重要。在这篇综述中，我们简要介绍了av3sb5的电子特性，特别侧重于角度分辨光发射光谱（ARPES）的见解。通过ARPES的镜头，我们揭示了kagome超导体sav3sb5的电子特性，这将为kagome相关物理学令人兴奋的新研究领域铺平道路。
The recently discovered layered kagome superconductorsAV3Sb5(A= K, Rb, Cs) have garnered significant attention, as they exhibit an intriguing combination of superconductivity, charge density wave (CDW) order, and nontrivial band topology. As such, these kagome systems serve as an exceptional quantum platform for investigating the intricate interplay between electron correlation effects, geometric frustration, and topological electronic structure. A comprehensive understanding of the underlying electronic structure is crucial for unveiling the nature and origin of the CDW order, as well as determining the electron pairing symmetry in the kagome superconductors. In this review, we present a concise survey of the electronic properties ofAV3Sb5, with a particular focus on the insights derived from angle-resolved photoemission spectroscopy (ARPES). Through the lens of ARPES, we shed light on the electronic characteristics of the kagome superconductorsAV3Sb5, which will pave the way for exciting new research frontiers in kagome-related physics.
