Fig. 2: The field-dependent Hall resistivity at different temperatures and doping densities.

The Hall resistivity for doping densities of (a) n0 = −3.0 × 1018 cm−3, (b) 1.0 × 1018 cm−3, and (c) 3.0 × 1018 cm−3, respectively. The dashed lines indicate the Hall resistivities that reverse sign with the increasing magnetic field. Temperature is varied from 35 K to 275 K at steps of 10 K. The relation between the temperature and color is indicated in the color bar.
