▎ 摘  要

The symmetry of surface states has been investigated with numerical calculations in graphene superlattices (SLs) terminated with magnetic cap layers. It is found that the surface states in SL of pure electric basis with cap layer of magnetic potential A(s) >= 0 are symmetric about the transverse wave vector k(y) = 0 plane to those with A(s)
