Conduction of surface electrons in a topological insulator with spatially random magnetization
arXiv:1907.05313 · doi:10.1103/PhysRevB.100.205428
Abstract
Using the Green functions method we study transport properties of surface electrons in topological insulators in the presence of a correlated random exchange field. Such an exchange field may be due to random magnetization with correlated fluctuations. We determine the relaxation time due to scattering from the magnetization fluctuations and from other structural defects. Then we calculate the longitudinal charge conductivity taking into account the contribution due to vertex correction.
