摘要：

Josephson junctions based on thin films of the Bi2Sr2Ca2Cu3O10 + delta compound show IcRn products compatible with YBa2Cu3O7 - delta samples. Using quasiparticle tunneling experiments we found evidence for a superconductor-insulator-superconductor tunneling process via localized states in the barrier. The Bi2Sr2CaCu2O8 + delta compound is investigated regarding possible applications in superconducting field effect devices. We present thin films of four unit cells thickness that are superconducting at 58 K. An inverted metal-insulator-superconductor structure was prepared. From the modulation of the normal slate resistance we estimate a carrier density of 7 x 10(19) cm for a superconducting sample. The shift of the transition temperature was 1 K/V. The modulation of the I-V characteristics was demonstrated. (C) 1999 Elsevier Science Ltd. All rights reserved.
