Аннотация Current density in superlattice placed in quantizing electric field and field of electromagnetic radiation has been calculated. The calculations were performed by taking into account an inelastic scattering of charge carriers by phonons. Possibility of the effect of absolute negative conductivity, i.e. the effect of appearance of electric current flowing in opposite direction than that of vector of quantizing electric field intensity, has been shown.
