▎ 摘　　要

Using first-principles calculation methods, we study the possibility of realizing a quantum anomalous Hall effect in graphene from stable 3d atomic adsorption via a charge-compensated n-p codoping scheme. As concrete examples, we show that long-range ferromagnetism can be established by codoping 3d transitionmetal and boron atoms, but only the Ni codopants can open up a global bulk gap to harbor the quantum anomalous Hall effect. Our estimated ferromagnetic Curie transition temperature can reach over 10 K for various codoping concentrations.
