Observation of Electronic Nematicity Driven by the Three-Dimensional Charge Density Wave in Kagome Lattice KV<sub>3</sub>Sb<sub>5</sub>
Kagome
superconductors AV3Sb5 (A = K, Rb,
Cs) provide a fertile playground for studying intriguing phenomena,
including nontrivial band topology, superconductivity, giant anomalous
Hall effect, and charge density wave (CDW). Recently, a C2 symmetric nematic phase prior to the superconducting
state in AV3Sb5 drew enormous attention due
to its potential inheritance of the symmetry of the unusual superconductivity.
However, direct evidence of the rotation symmetry breaking of the
electronic structure in the CDW state from the reciprocal space is
still rare, and the underlying mechanism remains ambiguous. The observation
shows unconventional unidirectionality, indicative of rotation symmetry
breaking from six-fold to two-fold. The interlayer coupling between
adjacent planes with π-phase offset in the 2 × 2 ×
2 CDW phase leads to the preferred two-fold symmetric electronic structure.
These rarely observed unidirectional back-folded bands in KV3Sb5 may provide important insights into its peculiar charge
order and superconductivity
