High-Q terahertz metamaterial from superconducting niobium nitride films
C. H. Zhang, J. B. Wu, B. B. Jin +5
We present in this letter terahertz (THz) metamaterials with low ohmic losses made from low-temperature superconductor niobium nitride (NbN) films. The resonance properties are cha…

Thermal Escape from a Metastable State in Periodically Driven Josephson Junctions
Guozhu Sun, Jian Chen, Weiwei Xu +7
Resonant activation and noise-enhanced stability were observed in an underdamped real physical system, i.e., Josephson tunnel junctions. With a weak sinusoidal driving force applie…

Controlling the Intrinsic Josephson Junction Number in a Mesa
Li-Xing You, Pei-Heng Wu, Wei-Wei Xu +2
In fabricating intrinsic Josephson junctions in 4-terminal mesa structures, we modify the conventional fabrication process by markedly reducing the…
