- Influence of current density on surface morphology and properties of . . .
The surface morphology is very rough at lower current density, but becomes smooth at higher current density, and exhibits pyramid type morphology at all the current densities The effect of current density on microhardness, melting behavior, and electrical resistivity are also reported here
- Digital Imaging Ch 7 Flashcards - Quizlet
Which of the following would lead to decreased density on an analog (film-based) image? increased base plus fog a low developer temperature extended processing time increased kVp
- Anomalous behavior of critical current in a superconducting film . . .
As the current density increases, the SC gap energy shrinks due to the momentum of the Cooper pairs, leading to a decrease in the condensation density of the SC state
- [1001. 1056] Thickness dependence of the critical current density in . . .
The thickness of the superconducting film determines the self-field and consequently the critical current density at zero applied field We find an equation, which derives the thickness dependence of the critical current density from its dependence on the magnetic induction
- Effect of current density on electroplated CoPt thick films
Films are electroplated using constant current density, ranging 25-200 mA cm 2, and subsequently annealed at 700°C for 40 min It is found that electroplating current density has a strong influence over the plating rate, surface roughness, grain size, and order parameter
- Critical-Current Behavior in Narrow Thin-Film Superconductors
At higher temperatures the observed critical current densities are significantly larger than the Bardeen-Rogers predictions based on calculations of the BCS energy-gap variation with current It is proposed that in these narrow films flux vortices due to the self-field of the current at the film edges are too large to enter the film and by
- Thickness dependence of the current density distribution in . . .
By means of a quantitative magneto-optical analysis, we show how the current density distribution is affected by sample thickness, due to geometrical effects and changes in microstructure We found a maximum into the critical current density for film thickness twice the London penetration depth
- Current sharing between superconducting film and normal metal - IOPscience
A two-dimensional model is introduced that describes DC current sharing between the superconducting and normal metal layers in a configuration typical of YBCO-coated conductors The model is used to compare the effectiveness of a surround stabilizer and a more conventional one-sided stabilizer
