The Progress and Potential Applications of Quantum Anomalous Hall Effect

Abstract

Quantum Hall effect is a very common research direction in recent years, many scientists have carried out in-depth research and experiments in this field. In this paper, the advancements and applications of the quantum anomalous Hall effect(QAHE) are being presented and discussed. Primarily, the principle and development of QAHE are analyzed. The QAHE is obtained by suppressing one of the edge states based on the quantum spin Hall effect(QSHE). The main experimental method is to add hybrid magnetic atoms in topological insulators. Since first successfully observed the phenomenon in 2013 by a Chinese group, multiple studies and experiments have been carried out on this kind of theory, and many equally important results have been obtained. Moreover, many application values and potentials of QAHE are explored. The research in this paper is helpful to deepen the understanding of the principle and experiment of QAHE and offer a guideline for further exploration.
