Smearing of the quantum anomalous Hall effect due to statistical fluctuations of magnetic dopants

By Zhiheng Yue and M. Raikh
Quantum anomalous Hall effect (QAH) is induced by substitution of a certain portion, x, of Bi atoms in a BiTe-based insulating parent compound by magnetic ions (Cr or V). We find the density of in-gap states, N(E), emerging as a result of statistic fluctuations of the composition, x, in the... Show more
