The magnetic field dependence of the hall coefficient in Germanium

The Hall coefficient RH of Ge specimens with doping concentrations between 1014 acceptors and 1015 donors per cm3 is determined as a function of magnetic field (2 × 10−3 to 15 T) in the temperature range from 30 to 250 K. At temperatures below 85 K a saturation value of RH at high magnetic fields is reached for all doping concentrations which is independent of specimen orientation. Empirical rules are derived for determining the exact carrier density from Hall effect measurements at medium and low magnetic fields.
