Phys. 97, 064108 (2005); Room temperature aging behavior of thermally imprinted Pt/SrBi 2 Ta 2 O 9 /Pt ferroelectric thin film capacitors Elementary Pt/ SrBi 2 Ta 2 O 9 / Pt ferroelectric capacitors have been structurally characterized by x-ray diffraction using highly brilliant synchrotron radiation. A microstructural analysis of the stacked layers was performed from the collection of high-quality one-dimensional and two-dimensional diffraction patterns. During x-ray diffraction experiments, peculiar electrical behaviors under irradiation were evidenced. Indeed, depending upon their initial state ͑poled or nonpoled͒, the capacitors have exhibited drastic changes in their electrical characteristics after or under irradiation, both "fatiguelike" ͑polarization reduction͒ and/or "imprintlike" ͑voltage shift͒ phenomena being observed. Using a sample environment specially designed to measure in situ the evolutions of ferroelectric characteristics, the kinetics of both degradation and restoration of ferroelectric properties of the SrBi 2 Ta 2 O 9 -based capacitors under x-ray radiation have been analyzed. Reduction and recovery of switchable polarization have been explained in terms of interaction between ferroelectric domain configuration and photoinduced charge carriers. Mechanisms of charge trapping proposed in the literature are discussed to explain aging and rejuvenation.[This article is copyrighted as indicated in the article.

REVIEW OF LITERATURE 4 electric hysteresis loop and the optical absorption spectrum in the wave length range of 0.43 to 0,70 jJi, Photomicrographs of the domain structure were made on each crystal before and after each irradiation. The objectives of this dissertation are to present data showing the changes in the hysteresis loop, optical absorption spectrum, and the domain structure of BaTiO^ as a function of Co^^ gamma dose and to "utilize these data to isolate the gamma radiation damage mechanism in BaTiO^. An additional objective is to compare the radiation sensitivity of crystals which were irradiated in the as-grown condition to that of crystals which had their surface layer removed by an etching process.
