Measurements on Two-Dimensional Arrays of Mesoscopic Josephson Junctions

T. S. Tighe

We report measurements on two-dimensional arrays of Josephson junctions with junction sizes down to 60 nm by 60nm. Due to their small size, these junctions belong to the class of mesoscopic systems: they show behavior which reveals the underlying quantum mechanical properties. Two energies characterize the junctions, the Josephson energy E (sub j) and the charging energy E (sub c). Arrays in which E (sub j) >> E (sub c) are superconducting around zero bias and at zero temperature, while arrays in which E (sub c) >> E (sub j), called charging arrays, are instead insulating. This is the basis of the superconductor-to-insulator (S-I) transition (Author)

Experimental Studies on Cooper Pair Transport in Josephson Junction Arrays

Takahide Yamaguchi, Hisao Miyazaki, Akinobu Kanda +1 more

We have investigated how the transport properties of small-Josephson-junction arrays vary depending on a quantum control parameter (the ratio of the Josephson coupling energy E J to the charging energy E C ), the magnitude of dissipation, and the dimensionality d of the system. We found that the arrays show Coulomb blockade behavior when R S is larger than about d R Q ( R Q ≡ h /4 e 2 =6.45 kΩ) and E J / E C is smaller than a threshold depending on the value of R S and the dimensionality. The result is discussed in terms of quantum phase transition induced by the charging effect and the dissipation.

Characteristics of Charging Effect in One-Dimensional Array of Bi2Sr2CaCu2O8+δ Intrinsic Josephson Junctions

Takeshi Kawae, Takashi Yasuda, Satoshi Awaji +3 more

For the observation of the charging effect on a Josephson junction, the charging energy (E c) must be much larger than the Josephson coupling energy (E J) and thermal energy (k B T). We investigated the properties of submicron-sized Bi2Sr2CaCu2O8+δ intrinsic Josephson junctions (IJJs) at low temperature. The current–voltage curve of IJJs with a junction area of 0.06 µm2 showed a much higher resistance state near the zero bias voltage regions when the measurement temperature decreased to 72.6 mK. The ratios of E c/E J and E c/k B T were 7.04 and 5.78, respectively, which indicates that the charging effect is dominant. In addition, a characteristic voltage structure due to the charging effect in one-dimensional junction array, which is composed of the offset voltage and the threshold voltage of the junction, was observed.
