Abstract
This study aimed to determine the effect of atomic fraction x of tellurium (Te) on the lattice parameters and the crystal structure of the Pb (Se, Te) compound prepared using Bridgman technique. Further characterization of the materials used X-Ray Difraction to determine the lattice parameters and the crystal structure. The chemical composition was determined using Energy Dispersive Spectroscopy (EDS), and the surface morfology shown by Scanning Electron Microscope (SEM). The results showed that all compounds crystallized in a cubic crystal structure and the lattice parameters of the crystal were a function of the fraction x of Tellurium atoms. EDS results showed that all samples were non stoichiometric but approached ideal composition. All compounds had identical surface because it had a cubic structure with homogeneous materials.
