Abstract :
In this paper, we report on the observation of the QHE in gated epitaxial graphene films on SiC (0001), along with pronounced Shubnikov-de Haas (SdH) oscillations in magnetotransport. The last QH plateau is especially pronounced, even at temperatures as high as 70 K, reaching the temperature limit of the present experimental setup.
