Low-Noise Hybrid Superconductor/Semiconductor 7.4 GHz Receiver Downconverter for NASA Space Applications
A low-noise microwave receiver downconverter utilizing thin-film high-critical-temperature superconducting (HTS) passive circuitry and semiconductor active devices has been developed for use in space.
Multilayer Buffer System for Fabrication of High-T(sub c) Edge-Geometry SNS Weak Links on Silicon-on Sapphire Substrates
High frequency detector and circuit applications often require device fabrication on medium-to-low-dielectric constant substrates.
Transition Edge YBa(sub 2)Cu(sub 3)O(sub 7-x) Microbolometers for Infrared Staring Arrays
High-temperature superconducting staring arrays are potentially important for both space and terrestrial applications which require the combination of high sensitivity over a broad wavelength range and relatively high temperature operation. In many such array applications sensitivity is more important than speed of response. Thus, it is desirable to design low-thermal-mass pixels that are thermally isolated from the substrate. To this end, Johnson, et al. at Honeywell have fabricated meander lines of YBCO sandwiched between layers of silicon nitride on silicon substrates. The silicon was etched out from under each YBCO meander line to form low-thermal-mass, thermally isolated microbolometers.
High-T(sub c) Edge-geometry SNS Weak Links on Silicon-on-sapphire Substrates
High-quality superconductor/normal-metal/superconductor(SNS) edge-geometry weak links have been produced on silicon-on-sapphire (SOS) substrates using a new SrTiO(sub 3)/'seed layer'/cubic-zirconia (YS2) buffer system.
YBa(sub 2)Cu(sub 3)o 7 -Based Edge-Geometry SNS-type Josephson Junctions with Various Normal Layers
High-quality, epitaxial superconductor(S)/normal(N)/S edge-geometry weak-link Josephson devices were fabricated.
Composition of Pulse-Laser-Deposited Y-Ba-Cu-O and Ba-K-Bi-O Thin Films
The composition of pulsed-laser-deposited Y-Ba-Cu-O and Ba-K-Bi-O thin films is shown to be strongly affected by target conditioning, gas pressure, and target-substrate distance.
