摘要

我们使用新开发的YBCO-BiO复合超导体开发了高阻抗约瑟夫森型探测器。结果表明，Bi2O3掺杂可提高探测器的正常电阻(Rn)，从而提高探测器的响应度(RMv)和噪声等效功率(NEP)。在Rn为13q的检测器上，RMV为I80 V/W, NEP为i4xio - 14w / V %。

High-sensitive Superconducting Microwave Detector Using YBCO-BiO Systems

We have developed a high impedance, Josephson type detector using a newly developed YBCO-BiO composite superconductor. It was found that the measured responsivity (RMv) and noise equivalemt power (NEP) could be improved by Bi2O3 doping, through enhancement of the normal resistance (Rn) of the detector. An RMV of I80 V/W and an NEP of I.4XIO-14 W/v% wele obtained with a detector having an Rn of 13 Q.
