Abstract
We report on the observation of quantized Hall plateaus in a system of two-dimensional Dirac fermions, implemented in a 6.6 nm HgTe quantum well at magnetic fields up to 34 T at nitrogen temperatures. The activation energies determined from the temperature dependence of the longitudinal resistivity are found to be almost equal for the filling factors nu of 1 and 2. This indicates that the large values of the g-factor (about 30-40) remain unchanged at very strong magnetic fields. (C) 2014 AIP Publishing LLC.
