Uniaxial negative thermal expansion in an orthorhombic superconductor CoZr3
Hiroto Arima, Tatsuki Inui, Aichi Yamashita +5
We investigated the temperature evolution of crystal structure of orthorhombic CoZr3, which is a superconductor with a transition temperature of 4.3 K, by synchrotron and laborator…
Observing and modeling the sequential pairwise reactions that drive solid-state ceramic synthesis
Akira Miura, Christopher J. Bartel, Yusuke Goto +11
Solid-state synthesis from powder precursors is the primary processing route to advanced multicomponent ceramic materials. Designing ceramic synthesis routes is usually a laborious…
Crystal Structure and Thermoelectric Transport Properties of As-Doped Layered Pnictogen Oxyselenides NdO0.8F0.2Sb1-xAsxSe2
Kota Morino, Yosuke Goto, Akira Miura +3
We report the synthesis and thermoelectric transport properties of As-doped layered pnictogen oxyselenides NdO0.8F0.2Sb1-xAsxSe2 (x < 0.7), which are predicted to show high-perform…
Effect of Bi Substitution on Thermoelectric Properties of SbSe2-based Layered Compounds NdOFSbBiSe
Yosuke Goto, Akira Miura, Chikako Moriyoshi +2
Although SbSe2-based layered compounds have been predicted to be high-performance thermoelectric materials and topological materials, most of these compounds obtained experimentall…
Synthesis, Crystal Structure, and Thermoelectric Properties of Layered Antimony Selenides REOSbSe2 (RE = La, Ce)
Yosuke Goto, Akira Miura, Ryosuke Sakagami +4
Inspired by the recent first-principles calculations showing the high thermoelectric performance of layered pnictogen chalcogenides, we experimentally characterise the crystal stru…
Synthesis, Crystal Structure, and Physical Properties of New Layered Oxychalcogenide La2O2Bi3AgS6
Yudai Hijikata, Tomohiro Abe, Chikako Moriyoshi +7
We have synthesized a new layered oxychalcogenide La2O2Bi3AgS6. From synchrotron X-ray diffraction and Rietveld refinement, the crystal structure of La2O2Bi3AgS6 was refined using…
Crystal structure, site selectivity, and electronic structure of layered chalcogenide LaOBiPbS3
Y. Mizuguchi, Y. Hijikata, T. Abe +10
We have investigated the crystal structure of LaOBiPbS3 using neutron diffraction and synchrotron X-ray diffraction. From structural refinements, we found that the two metal sites,…
Compositional and temperature evolution of crystal structure of new thermoelectric compound LaOBiS2-xSex
Y. Mizuguchi, A. Miura, A. Nishida +7
We examined the crystal structure of the new thermoelectric material LaOBiS2-xSex, whose thermoelectric performance is enhanced by Se substitution, by using powder synchrotron X-ra…
Structures and Optical Absorption of Bi2OS2 and LaOBiS2
Akira Miura, Yoshikazu Mizuguchi, Takahiro Takei +5
The band gaps of isostructural Bi2OS2 and LaOBiS2 were examined using optical absorption and discussed with the band structures calculated based on the crystal structures determine…
