Using the constant electron scattering time approximation, the appearance of a temperature gradient ( ∇ y T ) in a superlattice (SL) with current j z placed in a magnetic field H x = H and high electric field E x (the electric‐field‐induced Ettingshausen effect), is studied ( OX is the SL axis). The effect includes the Stark–cyclotron resonance leading to a non‐monotonous (and sign‐changing) dependence of the Ettingshausen effect on magnetic H and electric E x fields. The possibility of increasing the (transverse) thermoelectric effectivity at the expense of the field E x is taken into consideration.
