Piezoelectricity in perovskite-type pseudo-cubic ferroelectrics by partial ordering of off-centered cations
Autor: Yoshihiro Kuroiwa, Sangwook Kim, Ichiro Fujii, Shintaro Ueno, Yuki Nakahira, Chikako Moriyoshi, Yukio Sato, Satoshi Wada
Publikováno v: Communications Materials, Vol 1, Iss 1, Pp 1-8 (2020)
Strong piezoelectricity is typically due to reorientation of ferroelectric domains and is not expected in cubic systems. Here, the strong piezoelectricity of pseudo-cubic 0.3BaTiO3–0.1Bi(Mg1/2Ti1/2)O3–0.6BiFeO3 is explained in terms of partial or

Autor: Sangwook Kim, Ryuki Miyauchi, Yukio Sato, Hyunwook Nam, Ichiro Fujii, Shintaro Ueno, Yoshihiro Kuroiwa, Satoshi Wada
Publikováno v: Advanced Materials. 35
Piezoelectric materials play a key role in applications, while there are physically open questions. The physical origin of piezoelectricity is understood as the sum of contributions from intrinsic effects on lattice dynamics and those from extrinsic

Fabrication of layered hydroxide zinc nitrate films and their conversion to ZnO nanosheet assemblies for use in dye-sensitized solar cells
Autor: Takuya Yuki, Shintaro Ueno, Manabu Hagiwara, Shinobu Fujihara
Publikováno v: Journal of Asian Ceramic Societies, Vol 3, Iss 1, Pp 144-150 (2015)
Layered hydroxide zinc nitrate (LHZN; Zn5(NO3)2(OH)8·xH2O) films were fabricated on glass or plastic substrates by a chemical bath deposition method combined with a homogeneous precipitation in methanolic solutions. High- or low-temperature pyrolyti

Synthesis of Silver-Strontium Titanate Hybrid Nanoparticles by Sol-Gel-Hydrothermal Method
Autor: Shintaro Ueno, Kouichi Nakashima, Yasunao Sakamoto, Satoshi Wada
Publikováno v: Nanomaterials, Vol 5, Iss 2, Pp 386-397 (2015)
Silver (Ag) nanoparticle-loaded strontium titanate (SrTiO3) nanoparticles were attempted to be synthesized by a sol-gel-hydrothermal method. We prepared the titanium oxide precursor gels incorporated with Ag+ and Sr2+ ions with various molar ratios,
