Autor: Ran, Fan-Yong, Xiao, Zewen, Toda, Yoshitake, Hiramatsu, Hidenori, Hosono, Hideo, Kamiya, Toshio

Publikováno v: Sci. Rep. 5, 10428 (2015)

Tin monosulfide (SnS) is a naturally p-type semiconductor with a layered crystal structure, but no reliable n-type SnS has been obtained by conventional aliovalent ion substitution. In this work, carrier polarity conversion to n-type was achieved by

Beta-BaZn2As2 is known to be a p-type semiconductor with the layered crystal structure similar to that of LaZnAsO, leading to the expectation that beta-BaZn2As2 and LaZnAsO have similar bandgaps; however, the bandgap of beta-BaZn2As2 (previously-repo

Layered Compounds BaM2Ge4Ch6 (M = Rh, Ir and Ch = S, Se) with Pyrite-Type Building Blocks and Ge-Ch Heteromolecule-Like Anions

Autor: Lei, Hechang, Yamaura, Jun-ichi, Guo, Jiangang, Qi, Yanpeng, Toda, Yoshitake, Hosono, Hideo

Publikováno v: Inorg. Chem. 53, 5684-5691 (2014)

Structure and chemical features of layered compounds BaM2Ge4Ch6 (M = Rh, Ir; Ch = S, Se) synthesized under high-pressure and high-temperature method are systematically studied. These compounds crystallize in an orthorhombic phase with space group Pbc

Superconductivity of Ca2InN with a layered structure embedding an anionic indium chain array

Autor: Jeong, Sehoon, Matsuishi, Satoru, Lee, Kimoon, Toda, Yoshitake, Kim, Sung Wng, Hosono, Hideo

Publikováno v: Supercond. Sci. Technol. 27 (2014) 055005

We report the emergence of superconductivity in Ca2InN consisting of a 2-dimensional (2D) array of zigzag indium chains embedded between Ca2N layers. A sudden drop of resistivity and a specific-heat (Cp) jump attributed to the superconducting transit
