▎ 摘  要

We report magnetoresistance (MR) properties from room temperature (300 K) to 2 K in multilayered epitaxial graphene (EG) prepared on C-face of SiC substrate. A large (similar to 50%) and linear MR is observed at 300 K, which is distinctively different from other carbon materials. This linear MR is attributed to the two-dimensional (2D) transport in the material as inferred from our angular dependence magnetotransport experiments. Furthermore, negative MR behaviour at a low field regime for temperatures ]
