Abstract
AbstractData characterizing the stability of basic dielectric properties against thermal treatement are presented for crystals of TGS and deuterated TGS doped with alanine or bivalent platinum. Complex permittivity and over‐all polarization have been measured during a heating‐cooling cycle. In alanine doped crystals the heating and cooling curves are perfectly reproducible. In Pt‐doped samples the reproducibility is worse, for pure TGS the properties on cooling are strongly influenced by domain effects. These data made it possible to estimate the change of the figures of merit for pyroelectric ir detectors due to transient heating.
