Introduction. -- Photoemission Spectroscopy. -- Experimental Apparatus. -- CDW-Induced Band Modification in AV3Sb5. -- Effects of Cs Dosing and Nb Substitution to CsV3Sb5. -- Micro-ARPES Study of AV3Sb5. -- Summary.

This book presents high-resolution angle-resolved photoemission spectroscopy (ARPES) experiments on kagome superconductors KV3Sb5, RbV3Sb5, and CsV3Sb5-an ideal material family for studying rich physical phenomena originating from the geometric structure of kagome lattice-with the aim of elucidating the electronic structure and the origin of charge density wave (CDW) and superconductivity. The book begins with an introduction to kagome superconductors, followed by a description of ARPES which is the main tool used in the presented work in this book. The part of the experimental results consists of three chapters: The first chapter describes observation of low-energy excitations, Fermi-surface and momentum-dependent CDW gap by high-resolution ARPES on CsV3Sb5 and KV3Sb5; the second chapter shows evolution of electronic states upon alkali-metal dosing and isovalent substitution, and discusses their relation to modulation of physical properties; the other chapter provides the result of micro-ARPES on KV3Sb5, RbV3Sb5, and CsV3Sb5, and demonstrates the surface-termination- and alkali-metal-dependent three dimensional CDW character.
