High Chern number phase in topological insulator multilayer structures:A Dirac cone model study
文献摘要:
We employ the Dirac cone model to explore the high Chern number(C)phases that are realized in the magnetic-doped topological insulator(TI)multilayer structures by Zhao et al.[Nature 588 419(2020)].The Chern number is calculated by capturing the evolution of the phase boundaries with the parameters,then the Chern number phase diagrams of the TI multilayer structures are obtained.The high-C behavior is attributed to the band inversion of the renormalized Dirac cones,along with which the spin polarization at the Γ point will get increased.Moreover,another two TI multilayer structures as well as the TI superlattice structures are studied.
