| Abstract: | Iron pyrite(FeS_2) thin films have been prepared using screen print in this paper. x-ray diffraction (XRD) patterns are used to identify the crystal structure of the films. Diffraction peaks intensity, lattice constants and grain sizes changed with the film thickness have been discussed. The procedure used for this study is the full profile refinement of x-ray powder diffraction patterns using the Rietveld method. The S/Fe ratio,bond distances and angles of the samples have been determined. |
