Intrinsic magnetic topological insulator MnBi2Te4 found to have large bandgap in QAH state

A team led by researchers at Monash University has discovered an intrinsic magnetic topological insulator MnBi2Te4 with a large bandgap, making it a promising material platform for fabricating ultralow-energy electronics and observing exotic topological phenomena (Chi Xuan Trang et al, ‘Crossover from 2D Ferromagnetic Insulator to Wide Band Gap Quantum Anomalous Hall Insulator in Ultrathin MnBi2Te4’, ACS Nano 15 (2021), issue 8 (August), p13444). ..
