Aerosol Deposited Dielectric Ceramic Thick Films for Energy Storage Applications

Niklas Kyoushi-san from University of Kiel visited us and conducted experiments over a period of two weeks.

Our paper entitled “Large-area Release of Pb(Zr, Ti)O₃ Films with Reduced Crack Generation via Ferroelastic Domain Engineering” has been published in Small Struct. We demonstrated an approach for producing 200 nm-thick freestanding PZT membranes with reduced crack generation by achieving a single c-domain structure through ferroelastic domain engineering.

Our paper entitled “Substrate Dependence on the Growth of Defective-wurtzite Al₂S₃ Thin Films using Pulsed Laser Deposition” has been published in J. Ceram. Soc. Jpn. We demonstrated the Al₂S₃ can be grown epitaxially on α-Al₂O₃(0001) and SrTiO₃(111) using PLD.

A JST-ASPIRE workshop was held in Gamagori on Nov. 6–8. More than 70 participants from Japan (Institute of Science Tokyo, Kobe University, Osaka University, Osaka Metropolitan University, and Nagoya University), the United States (Pennsylvania State University, University of Pennsylvania, and Carnegie Mellon University), and Germany (NaMLab and Kiel University) gathered to discuss the development of novel ferroelectric thin films.

On Nov. 5, Dr. Uwe Schroeder and Dr. Roberto Guido (NaMLab, Germany) visited us and lectured on fluorite- and wurtzite-structured ferroelectrics.

Fluorite- and Wurtzite-Structured Ferroelectrics: From Fundamentals to Semiconductor Applications

Maxwell Tolchin-san from Pennsylvania State University visited us and gave a seminar.

Kosuke ONO won the presentation award of The 45th Electronics Division Meeting of the Ceramic Society of Japan held in Keio University, Japan for his presentation on fabrication of defective-wurtzite Al₂S₃ thin films.

Our paper entitled “Scandium-doped Aluminum Nitride Thin Films by Scanning Combinatorial Pulsed Laser Deposition” has been published in Jpn. J. Appl. Phys. We demonstrated the growth of highly-crystalized epitaxial AlScN thin films by using scanning combinatorial PLD.
