Overview

La₃TiSb₅ is a recently discovered layered Kagome-lattice compound that has drawn major attention for its nontrivial electronic topology, charge density wave (CDW) features, and potential superconducting behavior.
It belongs to the RTSb₅ (R = rare earth, T = transition metal) family, where geometric frustration and d–p orbital hybridization create ideal conditions for topological quantum states and unconventional superconductivity.

This compound serves as a key platform for studying band topology, correlated electron behavior, and lattice instability phenomena.
