Abstract
We prepared the Pb/Y2O3/Bi-Sr-Ca-Cu-O (BSCCO) specimens using the 80K-phase BSCCO single crystals and investigated the current-voltage characteristics. From the results, we found that Y2O3 was useful as an artificial barrier and that the native barrier was obtained by cleaving the BSCCO single crystals in air. The changes of the dI/dV-voltage characteristics of the Pb/air-cleaved surface(native barrier)/BSCCO specimen as well as the Pb/Y2O3(5OA)/BSCCO specimen were observed around ±3mV and ±25mV. The native barrier, which was removed by heating the BSCCO single crystals in vacuum at 300°C, is thought to be formed by the adsorption of gases.
