Chemical modification of silicene |
(a) Optimized structure of Fe–I in a 4×4 supercell with the Fe atom below the silicene plane, (b) the optimized structure of Fe–II in a 4×4 supercell with the Fe atom above the silicene plane, (c) the direction of the external electric field during the simulation of the magnetoelectric properties for doped silicene, (d) the magnetic moment of Fe-doped silicene for the 4×4 supercell as a function of the external electric field, and (e) the magnetic moment of Cr-doped silicene for the 4×4 supercell as a function of the external electric field.[ 57 ] |
