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…
Crystal Growth of BiSrCaCuO Whiskers from Pulverized Amorphous Precursors
Ryo Matsumoto, Sayaka Yamamoto, Yoshihiko Takano +1
High-transition temperature superconducting whiskers of BiSrCaCuO were successfully grown from pulverized amorphous precursors. The obtained whiskers reve…
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…
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…
