Implementation of self-consistent MGGA functionals in augmented plane wave based methods
Jan Doumont, Fabien Tran, Peter Blaha
Functionals of the meta-generalized gradient approximation (MGGA) are nowadays widely used in chemistry and solid-state physics for the simulation of electronic systems like molecu…
Bandgap of two-dimensional materials: Thorough assessment of modern exchange-correlation functionals
Fabien Tran, Jan Doumont, Leila Kalantari +8
The density functional theory (DFT) approximations that are the most accurate for the calculation of band gap of bulk materials are hybrid functionals like HSE06, the MBJ potential…
Validation of pseudopotential calculations for the electronic band gap of solids
Pedro Borlido, Jan Doumont, Fabien Tran +2
Nowadays pseudopotential density-functional theory calculations constitute the standard approach to tackle solid-state electronic problems. These rely on distributed pseudopotentia…
On the calculation of the bandgap of periodic solids with MGGA functionals using the total energy
Fabien Tran, Jan Doumont, Peter Blaha +3
During the last few years, it has become more and more clear that functionals of the meta generalized gradient approximation (MGGA) are more accurate than GGA functionals for the g…
Semilocal exchange-correlation potentials for solid-state calculations: Current status and future directions
Fabien Tran, Jan Doumont, Leila Kalantari +3
Kohn-Sham (KS) density functional theory (DFT) is a very efficient method for calculating various properties of solids as, for instance, the total energy, the electron density, or…
Limitations of the DFT-1/2 method for covalent semiconductors and transition-metal oxides
Jan Doumont, Fabien Tran, Peter Blaha
The DFT-1/2 method in density functional theory [L. G. Ferreira et al., Phys. Rev. B 78, 125116 (2008)] aims to provide accurate band gaps at the computational cost of semilocal ca…
