Evidence of two-dimensional flat band at the surface of antiferromagnetic kagome metal FeSn

Transition metal kagome compounds have been shown to host flat bands in their bulk electronic spectrum. Here, using planar tunnelling spectroscopy supported by first-principles calculations, the authors report the signature of a novel type of flat band at the surface of antiferromagnetic kagome meta...
