The investigation of the current density, the angular and energy distributions, as well as the field dependence of the exoemission arising under the pyro‐ and piezoeffect conditions, shows that the electron emission occurs from a dielectric layer on the ferroelectric surface. The effect of exoemission depletion is found. The mechanism of the exoemission phenomenon is examined. The calculations of the barrier permeability show that the exoemission represents the tunnel electron emission from the polaron band or from the bottom of the conduction band.
