Role of Delocalized Charges in the Pyroelectric Effect

Abstract

We show the temperature dependence of the pyroelectric effect and demonstrate how an increase in dark conductivity as a result of either trap depopulation or proton migration suppresses the pyroelectric-generated high voltage. Electrically shorting crystal z-surfaces coated with a transparent conductive layer is shown to be an effective way of eliminating the breakdown of the surface charge in air. A new method of measuring proton migration temperatures and nonradiative transitions is proposed.
