We report on the magnetotransport measurement on a single-layer graphene in pulsed magnetic fields up to B = 53 T. With either electron-or hole-type charge carriers, the Hall resistance R H is quantized into R H = (h/e 2)ν −1 with ν = ±2, ±6, and ±10, which demonstrates the observation of a half-integer quantum Hall effect (QHE). At B = 50 T, the(More)
