Quasiparticle trapping at vortices producing Josephson supercurrent enhancement
Yosuke Sato, Kento Ueda, Yuusuke Takeshige +6
The Josephson junction of a strong spin-orbit material under a magnetic field is a promising Majorana fermion candidate. Supercurrent enhancement by a magnetic field has been obser…
Half-Integer Shapiro Steps in a Short Ballistic InAs Nanowire Josephson Junction
Kento Ueda, Sadashige Matsuo, Hiroshi Kamata +6
We report on half-integer Shapiro steps observed in an InAs nanowire Josephson junction. We observed the Shapiro steps of the short ballistic InAs nanowire Josephson junction and f…
Ambipolar Transport in Narrow Bandgap Semiconductor InSb Nanowires
B. Dalelkhan, D. Göransson, C. Thelander +4
We report on transport measurement study of top-gated field effect transistors made out of InSb nanowires grown by chemical vapor deposition. The transistors exhibit ambipolar tran…
Dominant non-local superconducting proximity effect due to electron-electron interaction in a ballistic double nanowire
Kento Ueda, Sadashige Matsuo, Hiroshi Kamata +8
Cooper pair splitting (CPS) can induce non-local correlation between two normal conductors coupling to a superconductor. CPS into a double one-dimensional electron gas is an approp…
Anomalous modulation of Josephson radiation in nanowire-based Josephson junctions
Hiroshi Kamata, Russell S. Deacon, Sadashige Matsuo +6
We investigate the Josephson radiation of nanowire (NW)-based Josephson junctions in a parallel magnetic field. The Josephson junction made of an InAs NW with superconducting Al le…
Cooper-pair splitting in two parallel InAs nanowires
Shoji Baba, Christian Jünger, Sadashige Matsuo +9
We report on the fabrication and electrical characterization of an InAs double - nanowire (NW) device consisting of two closely placed parallel NWs coupled to a common superconduct…
