HIGH-RESOLUTION ELECTRON-MICROSCOPY OF THE HIGH-TC SUPERCONDUCTOR BI2+XSR2CA1-XCU2O8+SIGMA

Abstract:

The structure of the 85 K Bi-Sr-Ca-Cu-O superconductor has been investigated by means of high resolution electron microscopy combined with image simulation. An ordered one-in-five substitution of calcium by bismuth ions is proposed as the explanation for the observed superlattice formation. This model is consistent with the reports of the recent analytical studies carried out on the same system. The discovery of high temperature superconductivity in the Bi-Sr-Ca-Cu-O system has demonstrated c...
