摘要：

The electrophysical properties of semiconductor-superconductor sandwich pairs (InP-Bi/Pb 2223, 2234, 2245) are investigated, in which homophase superconductors based on bismuth cuprates with high reproducible critical temperatures of superconducting transition T-c = 107-180 K are used. The advantage of melt solar technology for obtaining superconducting materials is demonstrated. The microstructure and phase composition of strongly anisotropic superconductors with nominal composition Bi1.7Pb0.3Sr2Ca(n- 1)CunOy (n = 3, 4, 5) are researched. A technique of experimental determination of superconducting transition critical temperatures T-c in single-phase and homophase HTSC samples is presented. The current-voltage characteristics of InP-Bi/Pb pairs are investigated. The relationship between the electrical resistance of sandwich pairs and superconductor critical temperature T-c is established.
