Abstract: To study the solid state and chemical interactions between Y1Ba2Cu3O7-δand Si, resistivity and X-ray diffraction measurements were carried out onY1Ba2Cu3O7-δ–Sixcompounds with0 0.12. The transition temperatureTcwas found to be slightly decreased by Si addition up tox=0.08and sharply decreased atx=0.10. The superconducting phase incompletely disappeared atx=0.12. The resistivity was increased by Si doping and its behavior was changed from a metallic to an insulator and semiconductor-like nature. All peaks of the orthorhombic phase were still present by increasing the Si ratio and new phases were produced which were indexed as mainly barium silicates. Atx=0.12the orthorhombic phase was greatly decreased and the barium silicate phases were very clearly destroying the superconducting phase.The obtained results are discussed according to the superconductor–semiconductor composite model and with the idea of Bose–Einstein condensation. The superconductor–semiconductor composite as the YBCO–Si system seems to be a key to unlocking some secrets about the mechanisms of highTcsuperconductors.
