CsV₃Sb₅ (Cesium Vanadium Antimonide)

CsV₃Sb₅ is a layered kagome metal (AV₃Sb₅ family, A = K/Rb/Cs) in which the V atoms form an ideal kagome lattice. It brings together multiple correlated and topological phases in one system: a charge-density wave near 94 K, superconductivity around 0.9–2.5 K, topologically nontrivial bands, a giant anomalous Hall effect, and a chiral CDW that may break time-reversal symmetry. As a landmark kagome superconductor, it is a prominent system for studying CDW–superconductivity competition and the interplay of topology and correlation.

Growth method: Flux growth.

Sample specifications: Individual crystals measure approximately 3 mm, with a purity of up to 99.9999% (6N), and multiple high-quality single-crystal pieces included in each package.

Exfoliation: Moderate — exfoliable by mechanical exfoliation, but isolating thin flakes may require repeated cleaving or optimized methods.
