Transport properties of Nb/InAs(2DEG)/Nb Josephson field-effect transistors
Abstract
We investigate transport properties of mesoscopic semiconductor-superconductor weak links. The superconducting Nb electrodes of our junctions are coupled by the two-dimensional electron gas of an InAs heterostructure grown on a GaAs substrate. We report on the properties of Josephson field-effect transistors utilizing these junctions.
