This review aims to briefly outline the Hubbard-U scheme and to investigate the effect of its inclusion in standard Density Functional Theory on electronic, structural, and optical properties of ZnO wurtzite structure. To remedy the miscalculation of optimized lattice parameters determined by Local ...
E_{\rm{mid}} = \frac{(E_i+\delta{E})u_{E_i}(0)-(E_i)u_{E_i+\delta{E}}(0)}{u_{E_i}(0)-u_{E_i+\delta{E}}(0)} until the precision reach our setting (such as \delta{E} = 1.0\times 10^{-8}\, \, {\rm{a.u.}} ) After this refinement, we can obtain...
All the DFT calculations were carried on the Vienna Ab initio Simulation Package (VASP) by using spin-polarized DFT with the Hubbard model (DFT+U). The projector augmented-wave method and the Perdew–Burke–Ernzerhof exchange-correlation functional were applied. For a better description of Co 3d...
One possibility is to use U = 7.1 eV and J = 1.0 eV, giving Ueff = 6.1 eV, and the other choice is Ueff = 3.7 eV. Which value to choose strongly depends on the method used throughout the calculation (self consistency determination or not) and the property under investigation. Here, ...
