The Off-Stoichiometric Bi1.8Pb0.3Sr2Ca2Cu3.3Ox Target for Thin Films
نویسندگان
چکیده
X-ray diffraction (XRD), EDAX, AC susceptibility and resistivity measurements has been used as characterization methods for the Bi-2223 monophase target with the starting stoichiometry Bil.8F%,.3Sr2Ca2C~3.3 a. Pressure parameter is playing an important role in obtaining good superconducting properties for this compound. Critical currents and activation energy has been calculated from susceptibility and magnetoresistivity curves, respectively. The results could be interpreted in terms of TAPS and TAFF models.

Studies on Structural and Optical Characterization of In-Zn-S Ternary Thin Films Prepared by Spray Pyrolysis
Thin films of indium doped zinc sulfide (ZnS) for different indium (In) concentrations (x=0.0 - 0.8) were deposited onto glass substrate by spray pyrolysis method at 523K temperature. Aqueous solution of zinc acetate, indium chloride and thiorea were used to deposit the In-Zn-S film. The deposited thin films were characterized by Energy dispersive X-ray (EDX), Scanning electron microscopy (SEM)...

متن کاملCharacterization of Spray Pyrolysed CuInS2 Thin Films
An indigenously developed chemical spray pyrolysis system was used to deposit polycrystalline CuInS2 thin films. It was found that smaller spray rate results in films with better crystallinity and lower resistivity. Increase in surface roughness of the films was observed for higher spray rates. Variations in film stoichiometry with composition of spray solution were analyzed along with its opto...
