Quantum anomalous Hall (QAH) insulator with the largest energy gap

Quantum anomalous Hall (QAH) insulator with the largest energy gap. Based on the large gap quantum Hall (QSH) insulator Stanene [1], we proposed a QAH insulator with energy gap as large as 300 meV. Different from dilute magnetic doping, we introduce the ferromagnetism by creating Sn-pz dangling bonds in the honeycomb lattice. Strong exchange coupling and SOC lead to the QAH insulator [2].
