Depletion-mode 4H-SiC FETs were fabricated for use as harsh environment gas sensors. To enable sensitivity to NOx, O2 and H2 gases, metal oxide catalysts such as InOx were integrated into the gate of the device. The FETs had a total area of approxima

Dissipation and critical current densities in high- T c superconductors can depend on both intragranular flux creep and intergranular weak links. Separating these effects in polycrystals can be a formidable task. We present current-voltage data which

X-ray diffraction rocking curves are used to measure the c axis alignment of TlBa 2 Ca 2 Cu 3 O x films grown on polycrystalline substrates with thickness varying from 3 to 10.5 μm. Films thicker than 3 μm are found to contain two layers: a well al

Tape applications require high values of critical current density in thick films of TlBa 2 Ca 2 Cu 3 O y (Tl-1223). Previous work on polycrystalline YSZ substrates has shown average values of J c (77 K, 0 T) = 60 kA cm −2 for films 3–5 μm thick.

The electron backscattering pattern technique has been applied to the microstructural investigation of Tl(1223) thick films formed by vapor-phase thallination of Ag-containing Ba–Ca–Cu–oxide precursors. For samples grown on polycrystalline YSZ,

It is imperative for tape applications to produce thicker films of TlBa 2 Ca 2 Cu 3 O y with high critical current density on polycrystalline substrates (a useful figure of merit is the critical current per unit width, with a reasonable goal being 10

This paper reports a study of the microstructural evolution of Ag-containing 1223 Tl-Ca-Ba-Cu oxide superconductors in spray-deposited films. The films were formed by spray depositing nitrates of Ca, Ba, Cu, and Ag onto a polycrystalline yttria-stabi

X-ray microdiffraction has been used to map the orientational distribution of grains in a 4 × 5mm 2 polycrystalline film of Tl 1− y Ba 2 Cu 2 Cu 3 O x (Tl-1223) grown on yttira-stabilized zirconia (YSZ). The film consists of “colonies”, each c
