Automated Workflow for Non-Empirical Wannier-Localized Optimal Tuning of Range-Separated Hybrid Functionals
Stephen E. Gant, Francesco Ricci, Guy Ohad +3
We introduce an automated workflow for generating non-empirical Wannier-localized optimally-tuned screened range-separated hybrid (WOT-SRSH) functionals. WOT-SRSH functionals have…
Accurate Point Defect Energy Levels from Non-Empirical Screened Range-Separated Hybrid Functionals: the Case of Native Vacancies in ZnO
Sijia Ke, Stephen E. Gant, Leeor Kronik +1
We use density functional theory (DFT) with non-empirically tuned screened range-separated hybrid (SRSH) functionals to calculate the electronic properties of native zinc and oxyge…
Ultrafast Spontaneous Exciton Dissociation via Phonon Emission in BiVO
Stephen E. Gant, Antonios M. Alvertis, Christopher J. N. Coveney +3
Monoclinic bismuth vanadate (m-BiVO) is a promising indirect band gap semiconductor for photoelectrochemical water splitting, yet the characteristics of its low-lying photoexci…
Electronic and Optical Excitations in van der Waals Materials from a Non-Empirical Wannier-Localized Optimally-Tuned Screened Range-Separated Hybrid Functional
María Camarasa-Gómez, Stephen E. Gant, Guy Ohad +3
Accurate prediction of electronic and optical excitations in van der Waals (vdW) materials is a long-standing challenge for density functional theory. The recently proposed Wannier…
Optical absorption spectra of metal oxides from time-dependent density functional theory and many-body perturbation theory based on optimally-tuned hybrid functionals
Guy Ohad, Stephen E. Gant, Dahvyd Wing +6
Using both time-dependent density functional theory (TDDFT) and the ``single-shot" plus Bethe-Salpeter equation (-BSE) approach, we compute optical band gaps and optical a…
An Optimally-Tuned Starting Point for Single-Shot Calculations of Solids
Stephen E. Gant, Jonah B. Haber, Marina R. Filip +5
The dependence of ab initio many-body perturbation theory within the approximation on the eigensystem used in calculating quasiparticle corrections limits this method's predic…
Band gaps of crystalline solids from Wannier-localization based optimal tuning of a screened range-separated hybrid functional
Dahvyd Wing, Guy Ohad, Jonah B. Haber +4
Accurate prediction of fundamental band gaps of crystalline solid state systems entirely within density functional theory is a long standing challenge. Here, we present a simple an…
