| 摘 要： | 在没有外加磁场的作用下就能表现出量子化霍尔电导的量子反常霍尔效应已经成为霍尔家族中的重要一员,其物理起源是体能带反转结构和铁磁性相互作用.量子反常霍尔效应最重要的表现是在边缘态处具有无耗散运动的手性电流,这种性质拥有可以改变未来量子电子学的潜力,极大推动器件小型化、低损耗、高速率发展.近年来,基于理论指导,人们在实验上已多次观察到量子反常霍尔效应.在本文中,从实验层面上重点回顾了量子反常霍尔效应在铬(Cr)、钒(V)掺杂的(Bi, Sb)2Te3体系的研究进展,以及目前量子反常霍尔效应在其它体系中的研究现状,深入理解量子反常霍尔效应的起源和机理,最后对量子反常霍尔效应进行总结和展望.
