| contents | We investigate the topological properties of the vanadium-based 2D kagome metal ScV$_6$Sn$_6$, a ferromagnetic material with a magnetic moment of 0.86 $μ_B$ per atom. Using ab initio methods, we explore spin-orbit coupling-induced gapped states and identify multiple Weyl-like crossings around the Fermi energy, confirming a Chern number $|C| = 1$ and a large anomalous Hall effect (AHE) of 257 $Ω^{-1}$cm$^{-1}$. Our calculations reveal a transition from a topological semimetal to a trivial metallic phase at an electric field strength of $\approx$0.40 eV/Å. These findings position 2D ScV$_6$Sn$_6$ as a promising candidate for applications in modern electronic devices, with its tunable topological phases offering the potential for future innovations in quantum computing and material design. |
