KTaO3-Based Supercurrent Diode

Researchers have demonstrated the supercurrent diode effect (SDE) in KTaO3 (KTO) superconducting weak links (WLs) using conductive atomic force microscope (c-AFM) lithography. The SDE polarity can be controlled by varying the WL position, and the rectification efficiency reaches up to 13% under optimal magnetic field conditions.
