“…Little success has been achieved in obtaining high quality epitaxial perovskite PMN-PT films on a conductive electrode due to the appearance of stable pyrochlore phases. To achieve oriented, or even epitaxial films, the PMN-PT films are prepared on single crystal substrates, such as SrTiO 3 [3], Al 2 O 3 [4], and LaAlO 3 [5], that posses a crystal structure and lattice constants that approximate those of PMN-PT. However, single-crystal substrates are expensive and can only provide a small-sized geometry, which is contrary to Si technology that features lower cost, a larger area, and volume production.…”
