Profile 【 display / non-display

  • Akihiko Ito received the B.S., M.S., and Ph.D. degrees in engineering from Tohoku University, Sendai, Japan. His dissertation was on "Electrical Properties of Alkaline-earth Ruthenate Thin Films Prepared by Pulsed Laser Deposition". After a two-year post-doctoral appointment working on "Generation of Vector Laser Beam" at Institute of Multidisciplinary Research for Advanced Materials, Tohoku University, Japan, he joined Institute for Materials Research, Tohoku University, Sendai, Japan in 2009, where he was an assistant professor working on "Laser Chemical Vapor Deposition of Hard and Environmental Barrier Coatings" and "Spark Plasma Sintering of Transparent Ceramics and Composite Materials". He is currently an associate professor with Graduate School of Environment and Information Sciences, Yokohama National University, Yokohama, Japan. His current research interests include "Self-organized Nanostructured Ceramics for Structural and Functional Applications via Vapor Deposition Process with an Intense Laser Field" and "Chemical Vapor Deposition of Transparent Thick Films". Dr. Ito is a member of the Ceramic Society of Japan, the American Ceramic Society, the Japan Society of Powder and Powder Metallurgy, the Japan Society of Applied Physics, and the JSPS 124th Committee on Advanced Ceramics.

    <p>We prepared HfO<sub>2</sub>–Al<sub>2</sub>O<sub>3</sub> nanocomposite films using chemical vapor deposition. Fibrous and lamellar microstructures formed in the monoclinic and tetragonal HfO<sub>2</sub> (<i>m</i>/<i>t</i>-HfO<sub>2</sub>)–α-Al<sub>2</sub>O<sub>3</sub> films at deposition temperature of 1573 K and Al mole fraction in the precursor vapor of 36–74 mol %Al<sub>2</sub>O<sub>3</sub>. Characterization by electron microscopy revealed that the <i>m</i>/<i>t</i>-HfO<sub>2</sub> fibrous and lamellar structures are present throughout the α-Al<sub>2</sub>O<sub>3</sub> columnar matrix above 50 mol %Al<sub>2</sub>O<sub>3</sub> (55 vol %Al<sub>2</sub>O<sub>3</sub>), while α-Al<sub>2</sub>O<sub>3</sub> lamellar structure was formed in <i>m</i>-HfO<sub>2</sub> matrix below 50 mol %Al<sub>2</sub>O<sub>3</sub>.</p>

  • Precursor selection for metal–organic chemical vapor deposition of SrHfO3 films with Sr(dpm)2 and Sr(hfa)2

    S. Fujie, A. Ito

    Journal of the Ceramic Society of Japan ( 公益社団法人 日本セラミックス協会 )  129 ( 1 )   17 - 21   2021.01  [Refereed]

    Joint Work

     View Summary

    <p>SrHfO<sub>3</sub> films were prepared using metal–organic chemical vapor deposition (MOCVD) with hafnium tetrakis(acetylacetonate) and two different Sr precursors, and the effects of Sr content in the vapor and deposition temperature on crystal phase and microstructure were investigated. With the strontium bis(dipivaloylmethanate) [Sr(dpm)<sub>2</sub>] precursor, low Sr content of the deposited films regardless of Sr supply ratio resulted in no detectable SrHfO<sub>3</sub> formation. With the strontium bis(hexafluoroacetylacetonate) [Sr(hfa)<sub>2</sub>] precursor, along with linear increase of Sr content in the deposited films, the primary crystal phase of the film changed from monoclinic HfO<sub>2</sub> to orthorhombic SrHfO<sub>3</sub> to SrCO<sub>3</sub>. A single-phase orthorhombic SrHfO<sub>3</sub> film was prepared with the Sr(hfa)<sub>2</sub> precursor at 1373 K and 42 mol %Sr (corresponding to 50 mol %Sr in the film).</p>
