Two-dimensional honeycomb-kagome V2X3 (X = O, S, Se) with half-metallicity, high Curie temperature, and large magnetic anisotropic energy

Based on first-principles calculations, we predict a series of V 2 X 3 (X = O, S, Se) monolayers, which exhibit intrinsic ferromagnetic (FM) ordering and high Curie temperatures above room temperature.
