Designing Pseudopotentials

Pseudopotentials have greatly improved efficiency of DFT calculations by reducing the number of electronic states to be treated in the KS calculations. This is achieved by assuming that the "core" electrons' screening and scattering properties are generally invariant with the changes in the bonding nature of an atom. Our group has establshed means of improving transferability of these pseudopotentials across different atomic oxidation states and bonding environments. Here we provide a database of pseudopotentials in both the Local Density Approximation (LDA) and the Generalized Gradient Approximation (GGA) frameworks generated using the Rappe-Rabe-Kaxiras-Joannopoulos (RRKJ) method and employing augmentation functions, which we call as designed non-local pseudopotentials.
