Andreev reflection and bound state formation in a ballistic two-dimensional electron gas probed by a quantum point contact
Hiroshi Irie, Clemens Todt, Norio Kumada +4
We study coherent transport and bound-state formation of Bogoliubov quasiparticles in a high-mobility InGaAs two-dimensional electron gas (2DEG) coupled to a sup…

Josephson coupling through one-dimensional ballistic channel in semiconductor-superconductor hybrid quantum point contacts
Hiroshi Irie, Yuichi Harada, Hiroki Sugiyama +1
We study a superconducting quantum point contact made of a narrow InGaAs channel with Nb proximity electrodes. The narrow channel is formed in a gate-fitted con…
