Energy Functional of Orbital-Free Density Functional Theory for Sodium Metal Slab
摘要
Abstract
The method of using OF-DFT to study the ground-state density and work function of metal so-dium plates was explored.Through extensive numerical experiments,it was determined that a vW kinetic energy functional weight of 0.4 is required to obtain accurate ground-state properties for metal sodium plates,and this kinetic energy functional weight is applicable to different exchange-correlation potentials.关键词
