Perspective of Distortion and Vulnerability in Structure by Using the CdS-ZnS Composite Approach in Rietveld Refinement

Abstract

ZnS-CdS composite structure solid film was prepared by spry-pyrolysis technique. Structural analysis conducted using Rietveld refinement of PXRD pattern and FFT. From this, unit cells of the three phases with ZnSW(8H) (dominant) and others hexagonal and cubic CdS has been solved. Present work has done the tetrahedron analysis to study the distorted tetrahedrons. The limitations of highly distorted hexagonal phases innovatively examined in this paper, which has implemented an idea of the possible direction of tetrahedral distortions. From overall analysis, the structural perspective of spray pyrolysis made film has discussed in this paper along with SEM and UV-VIS data. In this work, the consideration of the assembly of ZnS-CdS composite is found practically very significant. It gives direct sub-structural contribution to understand the bigger composite structure with the details of tetrahedral level minute distortions which will be responsible for the single phase material of ternary-compound and showing its optical properties with semiconductor nature.
