摘要:

我们提出采用Bootstrap超导量子干涉器件(BS-SQUID,自举超导量子干涉器件)打破电荷输运的互易性。该器件利用磁通量反作用产生非互易的电流-电压特性,实现高达约95%的超流整流系数。BS-SQUID可作为准理想超流二极管(SD)工作,且在高达其临界温度约40%的温度下仍能保持效率。外部磁通量可用于调节或反转整流极性。最后,我们讨论了该超流二极管的有限电压工作区间,并提出该器件可作为微波频段的半波与全波信号整流器的潜在应用。

英文摘要:

We suggest using a device called the Bootstrap Superconducting Quantum Interference Device (BS-SQUID) to break the reciprocity in charge transport. This device uses magnetic flux back-action to create a nonreciprocal current-voltage characteristic, which results in a supercurrent rectification coefficient of up to approximately 95\%. The BS-SQUID works as a quasi-ideal supercurrent diode (SD) and maintains its efficiency up to about 40\% of its critical temperature. The external magnetic flux can be used to adjust or reverse the rectification polarity. Finally, we discuss the finite-voltage operation regime of the SD and present a possible application of our device as a half- and full-wave signal rectifier in the microwave regime.
