In this paper we explore the effects of open and shorted Josephson Junctions (JJs) on the current-voltage (I-V) curve, and the voltage-field (V-B) curve of two-dimensional high temperature superconductor (HTS) Gaussian distributed Superconducting Quantum Interference Device (SQUID) Arrays (SQAs). We examine two …

In this investigation we explore the effects of nonuniform magnetic bias fields on the voltage-flux curve of large two-dimensional arrays of superconducting quantum interference devices (SQUIDs). The SQUID arrays (SQAs) contain 1020 SQUIDs modeled with parallel coupling in the x-direction and series …

We examine the nature of thermal flow during the annealing process of a recently reported method to produce films of the high-Tcsuperconducting compound YBa2Cu3Oxwherein the oxygen content (x) spatially varies across the length of the sample. In this context, we discuss contrasting …

Abstract Large two-dimensional SQUID arrays were made using the step-edge Josephson junction process. The performance of the arrays is analyzed with respect to determining the conditions under which the optimal performance is achieved. We find that optimization of the field-voltage transfer function …

Comprehensive investigations of superconductivity in the charge-doped high-temperature superconducting cuprates often involve examining the evolution of physical properties within a series of samples having controlled variations of some dopant element---most frequently oxygen. Many important observations have been extracted from such experiments, however, …

Flux trapping in superconducting devices has shown to be detrimental to the consistent operation of superconducting electronics (SCE).Approaches to improve reliability of SCE components have focused on introduction of flux trap regions and highly elaborate degaussing procedures.Nevertheless, a controlled and reproducible method …

While state-of-the-art cryogenic receiver front end technology becomes more reliable and cost effective, the extent of actual performance gains still remains questionable and ill-defined. In order to support quantitative insight into cryogenic system deployment, this investigation explores the system performance characteristics of …
