SUMMARY
Has successfully analyzed the lattice parameter, error, and energy band gap of Cadmium Sulfide (CdS) material. CdS is a semiconductor material. In this study, the CdS used is a material with a cubic crystal structure using database from the International Center for Diffraction Data (ICDD), then the data is calculated using the Cramer-Cohen method. From these data the resulting lattice parameter of a = b = c = 5.823791777 Å with an average error of 0.00034%. The band gap energy calculation of CdS material is 2.477 eV.
