Abstract

The increasing technological advances in the computational field allowed the improvement in different fields of research, highlighting the Theoretical and Computational Chemistry, able to improve, induce and forecast new properties in materials with potential technological applications. Theoretical researchers have developed methods for computations using the first principles to solve problems in materials. Among the compounds of high technological performance we emphasize the sulfides in general, which have various applications, such as photoluminescence, electro-optical, electroluminescence, photo-catalysis and others. The objective of this project is applied the Theoretical and Computational Chemistry, in order to provide a better understanding of the physical, chemical and structural properties of the calcium sulfide. It will develop models and computer simulations to analyze the structural and electronic properties of this material in bulk and surface level. The results are discussed in terms of band structure, electron density of states and charge analysis. The results will be compared with experimental data found in the literature and developed in our laboratory.
