ScholarBank@NUS Repository. https://doi.org/10.1063/1.4765656 | Abstract: | 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 (∼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 20 K is recognised as a weak localization in EG. This study underlines the potential of exploiting multilayered EG on C-face SiC for room temperature magneto-electronic device applications. © 2012 American Institute of Physics. | Source Title: | Applied Physics Letters | URI: | http://scholarbank.nus.edu.sg/handle/10635/53010 | ISSN: | 00036951 | DOI: | 10.1063/1.4765656 |
