Thermoelectric power of nondegenerate Kane semiconductors under the conditions of mutual electron-phonon drag in a high electric field

摘要

The thermoelectric power of nondegenerate Kane semiconductors with due regardfor the electron and phonon heating, and their thermal and mutual drags isinvestigated. The electron spectrum is taken in the Kane two-band form. It isshown that the nonparabolicity of electron spectrum significantly influencesthe magnitude of the thermoelectric power and leads to a change of its sign anddependence on the heating electric field. The field dependence of thethermoelectric power is determined analytically under various drag conditions.
