Superconducting diode effect in artificial superlattices

Abstract

The superconducting diode effect (SDE) is a phenomenon that results in a superconducting state with zero electrical resistance in the forward direction, but a normal conducting state with finite resistance in the reverse direction. The similarity of this effect to the operation of a semiconductor diode, which is one of the building blocks of modern electronic devices. Exploiting the SDE is promising for the development of diodes and rectifiers with ultra-low power consumption. Recently, a method for controlling the zero-field SDE using magnetization has been demonstrated. This opens up new possibilities for using magnetization to control superconductivity. Here, we provide an overview of the SDE and discuss its future prospects.
