Micro-ARPES study of the kagome superconductor CsV<sub>3</sub>Sb<sub>5</sub>
ORAL
Abstract
We have investigated the electronic structure of the kagome superconductor CsV3Sb5 by micro-focused angle-resolved photoemission spectroscopy [1, 2]. We found evidence for the polar nature of the cleaved surface which is characterized by Cs- and Sb-terminated surfaces with markedly different fermiology.
In this presentation, we will show temperature dependence of the band structure for Cs- and Sb-terminated surfaces, and discuss the origin of the charge density wave.
