TL;DR: In this paper, a synchrotron x-ray study of lead titanate as a function of temperature and film thickness for films as thin as a single unit cell was performed.

TL;DR: In this article, the observation of periodic 180 degrees stripe domains below the ferroelectric transition in thin thin films was studied using x-ray scattering and the dependence of Lambda on d agrees well with theory including epitaxial strain effects, while the suppression of T(C) for thinner films is significantly larger than that expected solely from stripe domains.

TL;DR: The ionic conductivity of the nickelate perovskite is comparable to the best-performing solid electrolytes in the same temperature range, with a very low activation energy.

TL;DR: A significant lowering of the redox temperature by epitaxial stabilization of strontium cobaltites grown directly as one of two distinct crystalline phases, either the perovskite Sr coO(3-δ) or the brownmillerite SrCoO(2.5), providing useful information for developing highly sensitive electrochemical sensors and low-temperature cathode materials.

TL;DR: Using in situ high-resolution synchrotron x-ray scattering, the Curie temperature TC has been determined for ultrathin c-axis epitaxial PbTiO3 films on conducting substrates (SrRuO3 on SrTiO 3), with surfaces exposed to a controlled vapor environment.
