Developing a Superconducting diode based on the planar Josephson Junctions

Superconducting electronics offer energy efficiency and high-speed processing, making them a promising alternative to traditional semiconductor technology. While semiconductors have inherent limitations, superconductors have the potential to overcome these barriers and enable new opportunities. Diodes are essential components in both semiconductor and superconducting electronics. However, a fully efficient superconducting diode has not yet been realized. This work aims to develop a 100% efficient superconducting diode, which could revolutionize fields like quantum computing by utilizing the zero-resistance property of superconductors. Niobium-based Josephson junctions are strong candidates for creating such diodes due to their ease of fabrication and ability to achieve nonreciprocal behavior without requiring large magnetic fields or complex methods. Through the exploration of various designs and configurations, this study demonstrates strong nonreciprocal responses ranging from 80% to 100%, paving the way for industrial-scale applications.
