Our paper entitled “Significant Suppression of Island Growth in Epitaxial (Pb,La)(Zr,Ti)O3 Thin Films by Two-step Growth Technique” has been published in J. Ceram. Soc. Jpn. The initial low temperature deposition greatly suppressed the island growth of PLZT film, which is necessary for realizing thin film-based electro-optic devices.
