Preparation and Properties of High-T c Bi-Pb-Sr-Ca-Cu-O Thick Film Superconductors on YSZ Substrates

An evaluation of four firing profiles was performed to determine the optimum processing conditions for producing high-T c Bil.8Pb0.33Srl.87Ca2Cu30 x thick films on yttriastabilized zirconia substrates. Using these four profiles, the effects of sintering temperatures of 830-850°C and soak times of 0.5 to 12 hours were examined. In this study, Tc,zero values of 100K were obtained using a firing p...

TENSILE TESTING OF FREE-STANDING Cu, Ag AND Al THIN FILMS AND Ag/Cu MULTILAYERS

ÐFree standing polycrystalline thin ®lms with a strong h111i texture were tested in uniaxial tension. Studied were electron-beam deposited Ag, Cu and Al ®lms, and Ag/Cu multilayers consisting of alternating Ag and Cu layers of equal thickness, between 1.5 nm and 1.5 mm (bilayer repeat length, l, between 3 nm and 3 mm). The ®lms had a total thickness of about 3 mm. A thin polymeric two-dimension...

The Effect of Cu:Ag Atomic Ratio on the Properties of Sputtered Cu–Ag Alloy Thin Films

Cu-Ag thin films with various atomic ratios were prepared using a co-sputtering technique, followed by rapid thermal annealing at various temperatures. The films' structural, mechanical, and electrical properties were then characterized using X-ray diffractometry (XRD), atomic force microscopy (AFM), FESEM, nano-indentation, and TEM as functions of compositions and annealing conditions. In the ...
