Various novel physical properties have emerged in Dirac electronic systems,especially the topological characters protected by symmetry.Current studies on these systems have been greatly promoted by the intuitive concepts of Berry phase and Berry curvature,which provide precise definitions of the topological phases.In this topical review,transport properties of topological insulator (Bi2Se3),topological Dirac semimetal (Cd3As2),and topological insulator-graphene heterojunction are presented and discussed.Perspectives about transport properties of two-dimensional topological nontrivial systems,including topological edge transport,topological valley transport,and topological Weyl semimetals,are provided.
