Summary:
PioneerQ Josephson diode device with a multiple-layered nanostructured membrane design enabled aviation applications with high-efficiency high-frequency 500 Hz rectifications with 92% diode efficiency and 100% rectification energy efficiency at the 20 nA level with zero external power applied. When switches at low frequency, the device storage energy at 22.6-fold higher than the 5 µF/cm2 graphene supercapacitor. PioneerQ superconductive diode effect (SDE) devices worked at zero-field based on a multiple-layered superconductive nanostructured membrane formed hundred nanobridge diodes fabricated with organometallic materials on glassy carbon (GC) electrode with a configuration of S-I-M (memristive/memcapacitive) work at 500 Hz with 92.1% diode efficiency compared with a control device without SDE. The rectification energy efficiency results from ±5 mA to ±20 nA AC wave signals situations, and the output DC voltage is 41% and 100%, respectively compared with the diode commercial standard. The room-temperature (RT) high rectification ratio is 7.4x105 with a switch time from superconductive state to resistive state in 0.1 MHz under ±5 mA excitation. We first-time show the device functions as a supercapacitor when switching to low-frequency having 22.6-fold higher surface capacitance than a graphene supercapacitor.
