Two voltage jumps were found in the current–voltage characteristic of a thin superconducting film of Bi2Sr2CaCu2Ox at temperature 58 K. The fluorescent thermal imaging technique revealed a localized heat dissipation (hotspot) nucleated at the current causing the second jump, and the hotspots’ temperature is close to the critical temperature of the superconducting film. 相似文献

Hotspot formation is observed in a structured thin superconducting film of Bi2Sr2CaCu2Ox (BSCCO) using the fluorescent thermal imaging technique. The BSCCO film is deposited on SrTiO3 (STO) and has a superconducting transition at 80 K. A film of rare-earth doped polymer film deposited directly on the superconductor is used as thermal sensor down to 4 K. 相似文献
