Site-dependent conduction channel transmission in atomic-scale superconducting junctions
Howon Kim, Yukio Hasegawa
Using scanning tunneling microscopy, we reproducibly obtained electrical conductance spectra of superconductor- superconductor atomic point contacts formed on various atomic sites…
Electronic and magnetic influences of a stacking fault in cobalt nanoscale islands on the Ag(111) surface
Keiji Doi, Emi Minamitani, Shunji Yamamoto +4
Utilizing spin-polarized scanning tunneling microscopy and spectroscopy, we found coexistence of perpendicularly and in-plane magnetized cobalt nanoscale islands on the Ag(111) sur…
Site-dependent evolution of electrical conductance from tunneling to atomic point contact
Howon Kim, Yukio Hasegawa
Using scanning tunneling microscopy (STM), we investigated the evolution of electrical conductance between a Pb tip and Pb(111) surface from tunneling to atomic point contact at a…
Disorder-induced suppression of superconductivity in the Si(111)-()-In surface: Scanning tunneling microscopy study
Shunsuke Yoshizawa, Howon Kim, Yukio Hasegawa +1
The critical effect of disorder on the two-dimensional (2D) surface superconductor Si(111)-()-In is clarified by comparing two regions with different degree…
