The Thermoelectric Power in InSb in the Presence of an External Magnetic Field

Abstract
The thermoelectric power of n‐type indium antimonide is measured as a function of magnetic field up to 20 kOe. Saturation of the thermoelectric power is observed at high fields. The dependence of the electronic effective mass on the carrier concentration is derived from this experimental data. It is found that this dependence is in very good agreement with the non‐parabolic model of the conduction band. An analysis of the scattering processes indicates that optical mode and ionized impurity scattering are dominant at room temperature.
