Determined exoelectron emission effect in doped TGS

Abstract

The exoelectron emission from ADTGSP crystals has been investigated under pyroelectric effect conditions. It has been established that in doped crystals there is observed a reproducible emission effect. An equation for the depolarizing field determining the exoemission current has been derived. It is shown that in crystals with fixed domain structure near the Curie point the emission kinetics is limited by the temperature behaviour of the ratio / (where  is the pyroelectric coefficient,  is the dielectric constant).
