Computational Study for the Structural Change of the System CdTe_{1-x} S_x Thin Film

Authors: EMAD KHDAYER AL-SHAKARCHI

Abstract: Polycrystalline thin film of the graded system CdTe_{1-x}S_{x} for x=0,0.1,\ldots,1 are prepared by using thermal evaporation technique deposited on the glass substrate with an average thickness 3000 Å for each individual value of x . XRD technique is used with the aid of a computational program to study the phase change from cubic zinc blend structure to hexagonal wurtzite with an inversion point related to the x-value. It is found that x=0.1 gives us an inversion point in the structural change from cubic to hexagonal phase.

Keywords: Thin films, ternary compound, structural behaviour and miller indices
