中文摘要	量子霍尔效应是一种可以在宏观尺度出现的量子现象,由二维电子系统在强磁场下所具有的独特拓扑性质所引起.长期以来人们一直希望能够实现不需外磁场的量子霍尔效应,以便将其应用于低能耗电学器件.磁性拓扑绝缘体薄膜可能具有的量子化的反常霍尔效应即是一种可以在零磁场下出现的量子霍尔效应.本文介绍了拓扑绝缘体和量子反常霍尔效应的概念发展及量子反常霍尔效应如何在磁性掺杂拓扑绝缘体中实验实现,并探讨了量子反常霍尔效应在低能耗器件方面的应用前景.; The quantum Hall effect(QHE) is a quantum phenomenon that occurs on a macroscopic length scale as the result of the non-trivial topological property of a two-dimensional electron system in a strong magnetic field. It has long been expected that QHE can be realized without an external magnetic field such that the effect can be applied in electric devices that consume little energy. The zero-magnetic-field QHE can appear in thin films of magnetic topological insulators as the quantized version of the anomalous Hall effect; i.e., the quantum anomalous Hall effect(QAHE). Here, we review how the ideas of the topological insulator and QAHE were developed and how the QAHE was finally experimentally realized in thin films of a magnetically doped topological insulator. We also discuss the prospect of application of the QAHE in low-energy-consuming devices.
