Our paper entitled “Strong Impact of SrTiO3/TiO2 Buffer Layer on Epitaxial Growth and Dielectric Response of Ba0.7Sr0.3TiO3 Thin Films on MgO” has been published in Jpn. J. Appl. Phys. 270-nm-thick (001)-epitaxial BST films were deposited by pulsed laser deposition on STO/TiO2-buffered MgO with a SrRuO3 bottom electrode. It was found that the insertion of SrTiO3/TiO2 buffer layer enabled a two-dimensional growth of BST film, which resulted in the out-of-plane dielectric constant exceeding 1000.
