Substrate effects on intrinsic thermal stability and quench recovery for thin-film superconductors.

Type of article: Article

Summary

The results of calculations show that substrate effects exert significant influences on thermal stability of superconductors, because the higher thermal conductivity of substrates than those of films can cause heat feedback from the substrates. Both critical current densities related to intrinsic stability and recovery are calculated for different ratios of thermal conductivity and thickness of film to substrate, substrate materials, superconductors, Biot numbers, and operating temperatures.
