Title: Magnetizing topological surface states of Bi 2 Se 3 with a CrI 3 monolayer

Journal Article · · Science Advances

To magnetize surfaces of topological insulators without damaging their topological feature is a crucial step for the realization of the quantum anomalous Hall effect (QAHE) and remains as a challenging task. Through density functional calculations, we found that adsorption of a semiconducting two-dimensional van der Waals (2D-vdW) ferromagnetic CrI3monolayer can create a sizable spin splitting at the Dirac point of the topological surface states of Bi2Se3films. Furthermore, general rules that connect different quantum and topological parameters are established through model analyses. This work provides a useful guideline for the realization of QAHE at high temperatures in heterostructures of 2D-vdW magnetic monolayers and topological insulators.
