Quantitative structure-property relationship in a combinatorial Bi4-xLaxTi3O12 (0

A ferroelectric Bi4-xLaxTi3O12 (BLT) thin film library was fabricated from Bi2O3/La2O3/TiO2 multilayers using a multitarget RF-sputtering system equipped with an automated shutter. The polarization-electric field and structure were mapped as a function of the La content from x=0 to 1. Remnant polarization (Pr) increased as the La content decreased, and it reached a maximum 2Pr of 20 microC/cm2 at x=0.

Combinatorial approach for ferroelectric material libraries prepared by liquid source misted chemical deposition method.

Combinatorial approach for discovering novel functional materials in the huge diversity of chemical composition and processing conditions has become more important for breakthrough in thin film electronic and energy-conversion devices. The efficiency of combinatorial method depends on the preparation of a reliable high-density composition thin-film library. The physico-chemical properties of each sample on the library should be similar to those of the corresponding samples prepared by one-by-one conventional methods.
