Calculation of Carrier Doping-Induced Half-Metallicity, and Transformation of Easy Axis in Two-Dimensional MSi2N4 (M = Cr, Mn, Fe, and Co) Monolayers

We study the stability, electrical properties, and magnetic properties of MSi2N4 (M = Cr, Mn, Fe, and Co) monolayers based on the density functional theory.Comment: 10 figure
