Scanning Tunneling Microscopy Characterization of UBiTe

ORAL

Abstract

Heavy fermion materials are a valuable platform to study the interplay between strong correlations and topology, such as in the Weyl-Kondo semimetals Ce3Bi4Pd3 and USbTe. We use scanning tunneling microscopy and spectroscopy (STM/S) to characterize the heavy fermion material UBiTe, which is isostructural to USbTe. We observe five distinct surface terminations with unique topographical and spectral features, including a flat band on the U surfaces and an unusual supermodulation on the Te surfaces.
