Realization of quantum anomalous hall effect at tens of kelvin by n-p codoping of topological insulators

With the support by the National Natural Science Foundation of China,the research teams led by Prof.Xu Xiaohong（许小红）at the School of Chemistry and Materials Science,Shanxi Normal University and Prof.Zhang Zhenyu at ICQD,University of Science and Technology of China used vanadium-iodine（Ⅴ-Ⅰ）codoped Sb2Te3 to realize high-temperature quantum anomalous Hall effect（QAHE）,which was
