Kazuki OKAMOTO won the best presentation award of The 37th Electronics Division Meeting of the Ceramic Society of Japan held in Kawasaki, Japan for his poster on the piezoelectric property of PZT nanorods.
Published: Effect of strain on electrocaloric effect
Our paper entitled “Experimental Study of Effect of Strain on Electrocaloric Effect in (001)-epitaxial (Ba,Sr)TiO3 Thin Films” has been published in Jpn. J. Appl. Phys. We experimentally demonstrated that the electrocaloric effect is maximized at around the ferroelectric-to-paraelectric phase transition temperature modified by the strain in the films.

Awarded: Daisuke KATO
Daisuke KATO won Presentation Award of The Annual Meeting of the Thermoelectrics Society of Japan 2017 (TSJ2017) held in Osaka, Japan for his poster “Realization and Thermal Stability Evaluation of Sb-doped Mg2Si with High carrier concentration (translated)”.
Published: Charge screening strategy for ferroelectric domain pattern control
Our paper entitled “Charge Screening Strategy for Domain Pattern Control in Nano-scale Ferroelectric Systems” has been published in Scientific Reports. We experimentally and theoretically demonstrated that the domain pattern in ferroelectric nanorods can be controlled by the charge screening state.

Published: Indirect measurements of electrocaloric effect in ferroelectric films by PUND method
Our paper entitled “Indirect Measurements of Electrocaloric Effect in Ferroelectric Thin Films by Positive-up-negative-down Method” has been published in J. Ceram. Soc. Jpn. PUND polarization measurement was employed to indirectly estimate the electrocaloric effect in ferroelectric films. By subtracting the conductive component from the observed charge profile, the electrocaloric effect was precisely determined.

Finalist: Shogo MATSUO
Shogo MATSUO was selected for a finalist of Student Poster Competition of The 2017 Joint IEEE ISAF-IWATMD-PFM held in Atlanta, USA for his presentation “Nonlinear Electric Field Dependence of Electrocaloric Effect in (001)-epitaxial (Ba,Sr)TiO3 Thin Films”.
Published: High carrier concentration in Mg2Si(1-x)Sb(x)
Our paper entitled “High Carrier Concentration in Mg2Si1-xSbx (0 ≤ x ≤ 0.10) Prepared by a Combination of Liquid-solid Reaction, Ball Milling, and Spark Plasma Sintering” has been published in Intermetallics. The carrier concentration approximately ten times higher than that previously reported was obtained.
