Room-Temperature Calcium Intercalation into Graphite Catalyzed by Sodium
Akira Iyo, Shigeyuki Ishida, Hiroshi Eisaki +2
Calcium (Ca) insertion into graphite (C) has been considered to require elevated temperatures, and its occurrence at room temperature (RT) has been regarded as highly unlikely. Her…
Direct laser micromachining of superconducting terahertz Josephson plasma emitters
Reo Yamaguchi, Takuma Sakurai, Kazuhiro Yamaki +6
We demonstrate a rapid, maskless fabrication method for superconducting terahertz Josephson plasma emitters (JPEs) based on direct ultraviolet laser micromachining of BiSrC…
Energy-Resolved Real-Space Imaging of Orbital Nematicity in an Fe-Based Superconductor
Asato Onishi, Zifan Xu, Cédric Bareille +7
Electronic nematicity in Fe-based superconductors is manifested by spontaneous rotational symmetry breaking and the formation of nematic domains with mutually orthogonal directions…
Rapid and Scalable Synthesis of Alkali Metal-Intercalated C Superconductors
Akira Iyo, Hiroshi Fujihisa, Yoshito Gotoh +4
Alkali metal-intercalated C, ( = K, Rb, Cs, and their combinations), holds significant potential for practical applications due to its high superconducting…
