Abstract :
A Peltier current lead was proposed to reduce heat leak from the current lead. We studied two experiments as the principle of the Peltier current lead. In the first experiment, we measured Peltier cooling temperatures and resistivity of the semiconductors and copper lead; the purpose of this was for comparison with the second experiment. In the second experiment, the high temperature superconductor (HTS) was cooling down for Peltier effect at 77 K. Those temperatures were small, because the figure of merit of semiconductors, BiSb (n-type) and BiTe (p-type) were not enough values to be cooling HTS
