Crystal Size Improvement of Bi-based Superconducting Whiskers under Stress-controlled Condition
Sayaka Yamamoto, Ryo Matsumoto, Shintaro Adachi +3
Using stress-controlled amorphous precursors, we have successfully grown large (Bi-based) high-transition tempe…
Role of the inner copper-oxide plane in interlayer Josephson effects in multi-layered cuprate superconductors
Y. Nomura, R. Okamoto, T. Mizuno +4
We find systematic signatures suggesting a different superconducting nature for a triple-layered cuprate BiSrCaCuO with respect to a double-layer through t…
Direct Patterning of Boron-doped Amorphous Carbon Using Focused Ion Beam-assisted Chemical Vapor Deposition
Ryo Matsumoto, El Hadi S. Sadki, Hiromi Tanaka +4
The deposition of boron-doped amorphous carbon thin films on SiO2 substrate was achieved via a focused ion beam-assisted chemical vapor deposition of triphenyl borane (C18H15B) and…
Mask-less Patterning of Gallium-irradiated Superconducting Silicon Using Focused Ion Beam
Ryo Matsumoto, Shintaro Adachi, El Hadi S. Sadki +4
A direct patterning technique of gallium-irradiated superconducting silicon has been established by focused gallium-ion beam without any mask-based lithography process. The electri…
Pressure-induced superconductivity in SnSb2Te4
Peng Song, Ryo Matsumoto, Zhufeng Hou +6
We report the discovery of a new superconductor from phase change materials SnSb2Te4. Single crystals of SnSb2Te4 were grown using a conventional melting-growth method. The sample…
Incoherent-coherent crossover and the pseudogap in Te-annealed superconducting FeTeSe revealed by magnetotransport measurements
Takumi Otsuka, Shotaro Hagisawa, Yuta Koshika +9
In this study, we conducted various magnetotransport measurements on FeTeSe single crystals from which excess iron was sufficiently removed. Our results revea…
Fabrication of Superconducting YBa2Cu4O8 Film via Coprecipitation
Hiroshi Hara, Shintaro Adachi, Ryo Matsumoto +3
We have successfully synthesized the c-axis oriented YBa2Cu4O8 (Y-124) film on a SrTiO3 (1 0 0) substrate via a coprecipitation and a dip-coating method. The precipitations includi…
Synthesis of Hg-based cuprate superconductors by CsCl flux additional method
Hiroshi Hara, Ryo Matsumoto, Shintaro Adachi +3
We have succeeded in the synthesis of Re-doped quickly by a sealed tube technique with a bit of CsCl flux. Powder X-ray diffraction measurement…
Data-driven Exploration of Pressure-Induced Superconductivity in AgInSe
Ryo Matsumoto, Hiroshi Hara, Zhufeng Hou +8
Candidates compounds for new thermoelectric and superconducting materials, which have narrow band gap and flat bands near band edges, were exhaustively searched by a high-throughpu…
Pressure-induced Superconductivity in Tin Sulfide
Ryo Matsumoto, Peng Song, Shintaro Adachi +8
Tin sulfide (SnS) was successfully synthesized in single crystals by a melt and slow-cooling method. The obtained sample was characterized by an X-ray diffraction, an energy disper…
