Electric Control of Polarity in Spin-Orbit Josephson Diode
Electric Control of Polarity in Spin-Orbit Josephson Diode
The Josephson diode effect (JDE), characterized by a unidirectional supercurrent across a Josephson junction, arises from non-reciprocal critical currents typically controlled by magnetic fields. In this study, we demonstrate JDE controlled by local electric fields, achieving complete polarity reversal through gate voltages on epitaxial Al-InAs Josephson junctions. Our observations reveal …
