谐振型Josephson隧道结的频率特性(I)
FREQUENCY CHARACTERISTICS OF RESONANCE JOSEPHSON TUNNEL JUNCTIONS (Ⅰ)
【摘要】 本文沿用通常的电磁波谐振器品质因数Q的定义,结合约瑟夫逊隧道结的物理性质,提出了谐振型隧道结带宽的两种定义.报道了63个Pb-PbO_x-Pb隧道结谐振频率的测量结果,并报道了带宽测量的初步实验结果.讨论了该工作对约瑟夫逊电压基准的实用意义.
【Abstract】 Two definitions about the bandwidth of resonance tunnel junctions are suggested.The experimental results of the resonance frequency of 63 Pb-PbOx-Pb tunnel junctions and the primary measurements of the bandwidth are reported here.The practical significance of this work in Josephson voltage standard is recounted.
