The quantum anomalous Hall effect and strong robustness in two-dimensional p-state Dirac half-metals YX (Y = Li, Na; X = Se, Te)

Based on first-principles calculations, we have predicted a novel group of 2D p-state Dirac half-metal (DHM) materials, Y 3 X 2 (Y = Li, Na; X = Se, Te) monolayers. All the monolayers exhibit intrinsic ferromagnetism. Among them, Li 3 Te 2 and Na 3 Se 2 open topologically nontrivial band gaps of 4.0...
