Unprotected quadratic band crossing points and quantum anomalous Hall effect in FeB2 monolayer

Unprotected quadratic band crossing points and quantum anomalous Hall effect in FeB2 monolayer

Quadratic band crossing points (QBCPs) and quantum anomalous Hall effect (QAHE) have attracted the attention of both theoretical and experimental researchers in recent years. Based on first-principle calculations, we find that the FeB2 monolayer is a nonmagnetic semimetal with QBCPs at K. Through sy...
