A three-dimensional (3D) Dirac semimetal is known as a 3D analog of graphene; its Fermi-arc-like surface states are attractive for spintronic applications and can potentially modulate graphene via interface engineering. Here, we report the asymmetric magnetotransport in graphene/Cd3As2 heterostructure devices. The electron transfer occurring at the graphene/Cd3As2 interface results in a strong n-type doping of graphene. The interfacial coupling between graphene and Cd3As2 also enables us to selectively pin the chemical potential of graphene. The asymmetrical magnetotransport near the zero Landau level in graphene suggests that the interfacial coupling between Cd3As2 and graphene can be modulated by the magnetic field.A three-dimensional (3D) Dirac semimetal is known as a 3D analog of graphene; its Fermi-arc-like surface states are attractive for spintronic applications and can potentially modulate graphene via interface engineering.
