Abstract

Abstract In layered structures a longitudinal temperature gradient or a transverse electric current in a longitudinal magnetic field can give rise to internal currents. Due to the Peltier effect, these currents give a convective contribution to the thermal conductivity or produce a temperature gradient in the direction normal both to the current and to the magnetic field (in the geometry of the Ettingshausen effect). Circular currents in the coordinate—energy space can arise in quantum wells due to different responses of carriers of different subbands to a longitudinal temperature gradient.
