New kagome prototype materials: discovery of KV3Sb5,RbV3Sb5, and CsV3Sb5

In this work, we present our discovery and characterization of a new kagome prototype structure, ${\mathrm{KV}}_{3}{\mathrm{Sb}}_{5}$. We also present the discovery of the isostructural compounds ${\mathrm{RbV}}_{3}{\mathrm{Sb}}_{5}$ and ${\mathrm{CsV}}_{3}{\mathrm{Sb}}_{5}$. All materials exhibit a... View More
