Effect of fluorine doping on phase formation and properties of Bi(Pb)-2223 ceramics
(Elsevier Science Bv, 2011)
Superconducting ceramics of Bi1.6Pb0.4Sr2Ca2Cu3OyFx (x = 0-0.6) are prepared in air by conventional solid state reaction and characterized. The study shows that the melting point of the samples decreases as fluorine content ...
Fabrication of p-type CuSCN/n-type micro-structured ZnO heterojunction structures
(Elsevier Science Sa, 2011)
Micro-sized ZnO rods on a SnO2 coated glass substrate were obtained by the spray pyrolysis method. Then a p-type CuSCN layer was deposited on this micro-sized n-ZnO to produce a p-n heterojunction. Temperature dependent ...
Structural and electrical properties of cerium doped Bi(Pb)-2212 phases
In this work, a comparative study on the effect of doping by low content cerium at Ca site of Bi(Pb)-2212 phases is presented. Superconducting ceramics of nominal compositions Bi2Sr2Ca1-xCexCu2O8+delta (called CC series) ...
Comparative study of nano-sized particles CoFe2O4 effects on superconducting properties of Y-123 and Y-358
The effects of nano sized CoFe2O4 particles (10 nm) addition on the structural and the normal state resistivity of YBa2Cu3O7 (noted Y-123) and Y3Ba5Cu8O18 (noted Y-358) polycrystalline were systematically studied. Samples ...
Effect of ZrO2 Addition on Microstructure, Transport and Magnetic Properties of Bi2Sr2CaCu2O8+delta System
The influence of zirconium (Zr) addition to the Bi2Sr2CaCu2O8+delta (Bi2212) system on its phase formation, microstructure, transport, and magnetic properties is investigated. Samples have been characterized by means of ...
