Magnetic Field Dependence of the Seebeck Effect in Germanium

The thermoelectric power (Seebeck effect) of $n$-type Ge single crystals has been measured as a function of magnetic field at four temperatures ranging from 78°K to 278°K. At all temperatures the magnitude of the thermoelectric power increased with magnetic field. Such behavior is shown to be consistent with a simplified model of a semiconductor. It was also observed that to within ½% the thermal conductivity of Ge did not change as the magnetic field increased from zero to 11 500 oersteds.
