Superconductivity in Se-doped La2O2Bi2Pb2S6-xSex with a Bi2Pb2Ch4-type thick conducting layer
Rajveer Jha, Yosuke Goto, Tatsuma D. Matsuda +2
La2O2Bi2Pb2S6 is a layered Bi-based oxychalcogenide with a thick four-layer-type conducting layer. Although La2O2Bi2Pb2S6 is a structural analogue of La2O2Bi3AgS6, which is a super…
Growth of superconducting Sm(O,F)BiS2 single crystals
Koki Kinami, Yuji Hanada, Masanori Nagao +6
Superconducting Sm(O,F)BiS2 single crystals were successfully grown using KI-KCl flux. The obtained single crystals were flat-shaped and their size was 500um. The structure and com…
High-pressure synthesis and superconducting properties of NaCl-type In1-xPbxTe (x = 0-0.8)
Masayoshi Katsuno, Rajveer Jha, Kazuhisa Hoshi +3
We have investigated the Pb-substitution effect on the superconductivity of NaCl-type In1-xPbxTe samples obtained using high-pressure synthesis. Polycrystalline samples with x = 0-…
Improvement of superconducting properties by chemical pressure effect in Eu-doped La2-xEuxO2Bi3Ag0.6Sn0.4S6
Rajveer Jha, Yosuke Goto, Ryuji Higashinaka +4
We have investigated the substitution effect of Eu on the superconductivity in La2-xEuxO2Bi3Ag0.6Sn0.4S6. Recently, we reported an observation of superconductivity at 0.5 K in a la…
Enhanced superconductivity by Na doping in SnAs-based layered compound NaSnAs
Hao Yuwen, Yosuke Goto, Rajveer Jha +6
Superconducting transition temperature (Tc) reported in SnAs-based layered compound NaSnAs varies from 1.2 to 1.6 K, implying that its superconductivity is critically sensi…
Enhanced thermoelectricity by controlled local structure in bismuth-chalcogenides
K. Terashima, Y. Yano, E. Paris +7
Spectroscopic techniques, including photoelectron spectroscopy, diffuse reflectance, and x-ray absorption, are used to investigate the electronic structure and the local structure…
Effect of Indium doping on the superconductivity of layered oxychalcogenide La2O2Bi3Ag1-xInxS6
Rajveer Jha, Yosuke Goto, Tatsuma D Matsuda +2
We report on the substitution effect of Indium (In) at the Ag site of layered oxychalcogenide La2O2Bi3Ag1-xInxS6. The Tc decreases with increasing In concentration. A hump in the n…
