| The quantum anomalous Hall effect will play a special role in electronic devices in the future. It can be used to manufacture electronic devices with low energy consumption and high speed, so as to promote the progress of information technology. We obtain some properties of the two-dimensional organic material T(C6H5)3 (T = V, Mn, Fe, Tc, Re) by first-principles calculations. We find that the 2D organic material is a Dirac semimetal in the absence of spin-orbit coupling. When the spin-orbit coupling is included, the Dirac semimetal will evolve into a topological insulator with a quantum anomalous Hall effect. Our work provides a platform to realize topological insulators in the two-dimensional organic. |
