Abstract

MgO thin films were grown on highly oriented pyrolytic graphite (HOPG) and (001)-oriented diamond substrates by molecular beam epitaxy. The crystal structure of MgO was characterized by reflection high-energy electron diffraction and X-ray diffraction. We found that the MgO grew as (001)- and (111)-oriented textured structures on the HOPG and diamond substrates, respectively. The MgO(001) showed a smaller misalignment of the crystal orientation on the HOPG than on amorphous CoFeB, which indicates that the MgO(001) on graphene can be useful as a tunnel barrier for efficient spin injection into semiconductors.
