Fabrication and study of characteristics of HgSr₂ Ca_n-1Cu_nO_d+10, (n=1, 2 and 3) thin films superconducting

Recently, particular attention has been given to the material of Superconducting films because of its exceptional electrical and optical properties. In this work, HgSr2 Can-1CunOd+10, (n = 1, 2 and 3 ) .Thin Films Superconducting have been prepared by two-step process bulk and thin film. The optical properties were calculated absorption, transmission, reflection, band gap, coefficient of absorption, excitation coefficient and index of refraction in the range of wavelengths (300-1100) nm using a double beam spectrophotometer (UV/VIS). Structural, morphological, and electrical properties were investigated using X-ray diffraction (XRD) and AFM, Using the 4-probe technique measuring the resistivity as a function of temperature. The composite HgSr2 Ca2Cu3Od+10 showed an improvement in all properties the structural, electrical and optical as a result of increasing of Cu-O layers.
