VASP

source:beike new material Views:6016time:2020-08-10 QQ Academic Group: 1092348845

Density functional theory has achieved great success in the field of theoretical chemistry, providing detailed information on the structure of adsorbed reactants on the surface, adsorption sites, and interaction remodeling. Kohn and Pople have made great contributions in this field. Received the 1998 Nobel Prize in Chemistry.
The development of DFT calculation makes it possible to understand the microstructure and reaction mechanism of the catalyst from the atomic scale of the electron. It has become an important auxiliary means for studying the microstructure and chemical reaction mechanism of the chemical system, for a better understanding of the catalytic reaction process and reaction mechanism, and Designing efficient catalysts provides reliable theoretical support.
In the field of material computing, VASP is one of the most popular commercial software used in material computing. In the following 11 cases, there are 8 VASP calculations. It is called the "Vienna Ab-initio Simulation Package" and was developed by the Hafner team at the University of Vienna. VASP can perform electronic structure and molecular dynamics simulation, can calculate the geometric properties of materials (bond length, bond angle, lattice constant), electronic structure properties (electronic state density, band structure, electron density distribution, electronic local function) , optical properties (dielectric constant, absorption spectrum, refractive index) and magnetic properties.
VASP is powerful but shortcoming in that it does not have a good interface. MedeA has successfully solved this problem. It is a platform software that integrates the most advanced quantum mechanical VASP and molecular dynamics LAMMPS programs. Create models, set parameters and visual results analysis under Windows system, easy to use, MedeA is powerful and has no pirated resources.
