Abstract

A quaternary structure of Zn:Cd:S:Cu thin films were prepared by
chemical spray pyrolysis method with different concentration of Zn and Cu
in the solution . The structure and the component were examined by X-ray
diffraction , which obtained that all the prepared thin films are
polycrystalline and have many phases . The optical characteristics were
measured by using a Uv-Vis. Spectrophotometer from the absorption and
reflectance spectra within the range (200-1000 nm), such as the energy gap
(Eg) , extinction coefficient (k) and the refractive index (n) . We found energy
gap changed with concentration and the components of the solution . The
value of the energy gap ranged between (1.6-2.5 eV) and the high value of the
extinction coefficient given when the quantity of Zn equal to 20ml in the
solution and this value equal to 0.55 at wavelength equal 550nm . Also the
value of refractive index takes a wide range, it's value decreased when the
quantity of Zn was increased . From the D.C. conductivity measurements at
the range (295-475K) obtained that the films have two activation energies
varied with the variation of the temperature and the concentration of the
elements in the compound . From the Hall effect measurements all films
which doped by Cu were p-type .
