研究了螺旋磁化超晶格对三维拓扑绝缘体表面电子态的影响。结果表明，该超晶格系统的能谱只有两个狄拉克点，但有许多半狄拉克点
We investigate the effect of a spiral magnetization superlattice on the surface electronic states of a three-dimensional topological insulator. It is shown that the energy spectrum of this superlattice system has only two Dirac points but many semi-Dirac
