Scanning Tunneling Microscopy and Spectroscopy Study of the Kagome Metal EuTi ₃ Bi ₄

We report scanning tunneling microscopy and spectroscopy on the kagome metal EuTi 3 Bi 4 . Cleavage produces atomically flat Eu-terminated surfaces. Spectroscopy shows characteristic states from van Hove singularities and flat bands. Quasiparticle interference imaging reveals C 2 -symmetric patterns that evolve with energy, reflecting the electronic anisotropy and band dispersion expected for the kagome-derived surface states. This study provides a real-space view of the surface electronic structure in EuTi 3 Bi 4 .
