Density Functional Theory Calculation Service
In the modern scientific landscape, computational modeling plays a pivotal role in understanding and predicting material properties, molecular interactions, and chemical reactions. At CD ComputaBio, we specialize in density functional theory (DFT) calculations, a powerful quantum mechanical method used widely in chemistry, physics, and materials science. Our DFT calculation service is designed to provide researchers and organizations with reliable, high-precision computational insights that support both fundamental research and practical applications.
Introduction to Density Functional Theory Calculation
DFT provides a theoretical framework for calculating the electronic structure of atoms, molecules, and solids. It is based on the principle that the ground-state properties of a system can be determined by its electron density. By solving the Kohn-Sham equations, DFT can accurately predict a wide range of properties, including electronic band structures, optical properties, magnetic properties, and chemical reactivity.
