The capability of an all-niobium superconducting quantum interference device (SQUID) array to operate as an electrically small antenna capable of detecting radio frequency from distant sources was demonstrated. The measurements were performed in thre

Several novel techniques are now available to dramatically increase the grain size of epitaxial Rare-earth-BCO films so they are effectively single crystals. Our motivation is to use single-crystal films for base electrodes of edge SNS junctions to i

Careful studies of the corrosion, redox, galvanic, and oxygen evolution/uptake reactions associated with YBa2Cu3O7–δ and related compounds have been completed. These studies have led to an understanding of the many factors that contribute to the p

HTS SFQ digital circuit applications require high resistance HTS Josephson junctions. We have investigated the factors affecting the resistance of SNS edge junctions which use Co-doped Y-Ba-Cu-O as the normal metal layer. Several parameters are found

We have fabricated high-T/sub c/ SNS weak links in an edge geometry with integrated YBa/sub 2/Cu/sub 3/O/sub x/ (YBCO) groundplanes and SrTiO/sub 3/ insulators, using a process which incorporates six epitaxial layers, including a Co-doped-YBCO normal

We have fabricated and measured high T/sub c/ superconductor single flux quantum 1-bit flux-counting analog-to-digital converters (ADCs). The ADCs were made with a multilayer all-epitaxial process which incorporates 10 edge SNS (superconductor-normal

Utilization of the high temperature superconductor, YBa 2 Cu 3 O 7−δ , in commercial applications is becoming increasingly feasible. Before full advantage of this material can be taken, however, the lifetime, oxygen stability and processability of

We have successfully fabricated and tested a high temperature superconducting (HTS) sigma-delta modulator for analogue-to-digital conversion. This is the first demonstration of a GHz sampling A-to-D in HTS. The 15-junction single-flux-quantum (SFQ) c
