Abstract

The study of hybrid superconductor-semiconductor (S-Sm) structures has​ received renewed interest because of the recently reported detection of Majorana fermions at the S-Sm interface in nanowire and topological insulator based devices. Here, we report the experimental results on proximity-induced superconductivity in a high-mobility two-dimensional electron gas (2DEG) in InGaAs heterostructures. Eight symmetric S-Sm-S Josephson junctions were fabricated on a single InGaAs chip.
